Slick to Full Loadout: Building a Scalable and Modular Armor System

By Eric S.

Mayflower Low-Profile Armor Carrier

When I attended SOFIC in 2011, I was impressed with the ECLiPSE line of armor carriers by BAE Systems. Going to a modular vest system totally made sense to me as I was then working in a street crimes unit which had us in both uniform and plain clothes assignments. The issue I kept running into had been scaling up and down from an under shirt ballistic vest, outer vest carrier and rifle plate carrier. Throwing my plate carrier over my uniform vest was no problem but there was no way to wear it over the outer vest carrier. Switching around with these different vest systems was a real PITA and not very practical.

The same issues arose in my plain clothes assignment, so I started my search for some type of modular setup. The BAE system is now nowhere to be found and hence the problem with the larger industrial military companies like BAE. Being large is great for the military, but with smaller ventures like the ECLiPSE line being either pushed between its subsidiaries or sold outright, those products may never reach the Law Enforcement or civilian side.

My Requirements

My requirements in a new vest system were pretty bold. Here’s what I needed a single vest to do without being “custom made” to keep costs down:

  • Be able to carry “police cut” soft armor and be able to scale up to armor plates. Soft armor plate backers don’t give enough coverage for Police work in my opinion and the soft armor cut had to be reasonably concealable. 
  • Be sustainable for armor upkeep/upgrade. I wanted a soft armor cut that will be made 10 or 15 years from now (we’ll see if this works out.) No “custom” cuts, which would lead to added expense and time delays in the future. For those of you that get measured for a vest every five years, you know how long you have to wait to get your new vest. The SPEAR cut soft armor was an option in this area.
  • Be able to scale from a “slick” rig all the way up to a tactical load out and all versions in between. This is what really narrowed things down. I didn’t want a vest with MOLLE/PALS all over, especially on the back as I never use it.
  • Have hook and loop for ID panels front and rear.
  • Have the ability to “clip-in” front panels (MOLLE panel, Hook and Loop panel and AR15 rifle panel.)
  • Be able to carry a radio and medical kit on the sides of the cummerbund at all times, without the front panel clipped in.

The Answer

Mayflower R&C

After much research my answer was found in the Mayflower Low-Profile Armor Carrier (with armor package). Bryan did a review in 2009 of the armor system which really helped with my final decision. The only other vest system which came close to my requirements was the Rogue Gunfighter LVR vest. I didn’t have a way of seeing one in person and I didn’t know of anyone who owned one, but it looked to be a good alternative. I would make sure to ask a bunch of questions about the soft armor though, as it appears to be a proprietary cut.

Once I narrowed down the Mayflower and Velocity soft armor I had to figure out what to do about making it modular. To start, I ordered the vest with the MOLLE/PALS mesh cummerbund, as I didn’t need the side plates and wanted to keep the bulk down. The only downside was that it only had 4 rows of webbing, which meant some items might hang off the bottom a bit. The ITS ETA Trauma Kit (I have the first generation version) and Blue Force Gear Ten-Speed are two examples. The MOLLE cummerbund allows me to run my radio and trauma kit on the vest at all times. The overall vest is low profile and provided excellent mobility which is a nice departure from my old vest that was full of MOLLE and very bulky.

Next I had to figure out what type of clip-in panels to run up front. I’m going to break the vest down into the various configurations and describe the how and why of each. I’m running Extreme Gear Labs VOCR clip-in panels and a Haley Strategic D3. There are other panels out there that will clip directly into the Mayflower vests, but Darrin at EGL has been great to do business with and his products are solid.

Setup 1 – Slick

Slick Setup

While I don’t intend to use the Mayflower as a typical “under uniform” vest, it can function very well in that area. Pictured is the Mayflower (right) compared to my issued PPE under uniform vest (now Point Blank). As you can see the Mayflower is pretty slim which is very impressive.

I think back to my days doing PSD missions and would’ve loved to have this type of setup. Our uniform requirements would change constantly going from diplomatic visits in a suit, to trips into Afghanistan. Trying to juggle all of this out of two suitcases at the hotel was challenging and more often than not we were under equipped in Afghanistan.

There’s no doubt you could run the Mayflower “slick” under a suit and in plain clothes. Then scale up to tactical missions in an overt type uniform.

Setup 2 – Semi-slick Surveillance

Slick Setup

In this setup just one of the MOLLE/PALS cummerbunds is used to support my radio and the other side is a low profile cummerbund. I leave the upper SwiftClips attached to the front and this creates the “slickest” version of the vest I’ve personally run. The great thing about the vest is you can quickly switch out the cummerbunds as needed.

I’m able to use my iPhone earbuds with this configuration which takes away issues of clipping on an earpiece. Routing the earpiece cables and radio mic on the low profile shoulder straps can sometimes be a problem. I’m not completely happy with my setup and using shoulder pads might alleviate the difficulty I’m having. As you can see in the photos, I’ve rigged it using hook and loop fasteners and an M4 magazine bungee strap for the mic. My point being is simply a warning that you may run into issues mounting comms on these shoulder straps, especially if you’re switching different types of earpieces around.


I use an old medical pouch to stow accessories in one place and mounted an old Eagle ID panel on the front which keeps a subdued Sheriff patch handy. Inside I keep the two low-profile cummerbunds, the hook backer for the D3 chest rig, the shoulder harness for the D3 and EGL hook-loop clip-in panel and a large subdued rear Sheriff patch. If needed, I could run the D3 or shotgun rig as a stand alone system.

Setup 3 – Vehicle & Jump Out

Vehicle Jump Out

This is the configuration I use the most. The main component of the setup is the EGL Variable Objective Chest Rig which is a MOLLE/PALS panel. This allows you to obviously use anything designed to mount to MOLLE/PALS.

In my case I needed access to my pistol, handcuffs, tourniquet and two pistol magazines. I was able to mount all of these items with no problem using this setup. I used a G-Code RTI “H-Mar” MOLLE adaptor for my pistol as I run a Glock 26 and a Glock 21. Two extremes in pistol sizes I know, but being able to run each one on the same vest is a good option.

For vehicle work, having a chest mounted pistol is a valid platform. What’s also great is being able to take the holster off the vest if I end up running the pistol on my belt which can cut down on the bulk up front. I’ve also seen people using the G-Code RTI to mount other items such as medical kits and magazine pouches like the HGSI Taco system. Think about being able to clip-in different panels and also different accessories, ultimate versatility!

I also needed a “admin pouch” for paperwork, a pen and other small items. This is where things got tricky as the Low-Profile carrier doesn’t have MOLLE/PALS on the upper part of the vest like the Assault carrier. This made mounting a typical admin pouch impossible. Enter the EGL Hook & Loop Admin Pouch which has a hook backing and fits snugly in place. Again, being able to take the admin pouch on and off adds to the versatility of the overall system.

Setup 4 – Shotgun

Shotgun Setup

Running a shotgun also? This is no problem thanks to the EGL VOCR-SLAPhappy. Simply put, this is a loop faced clip-in panel which allows mounting of any hook backed accessory. In my case I’m using two OSOE Shotgun cards and a Blue Force Gear Ten-Speed Triple Pistol Dapper. There are numerous ways you could set this up to run a shotgun, gas gun or other system.

Setup 5 – Haley Strategic D3 Chest Rig

D3 Front

For my rifle I’m using the Haley Strategic D3. The D3 is a perfect fit for the Mayflower vest and takes care of my rifle setup. I will admit right now Travis does a much better job than I could describing the D3 platform so I will humbly direct you to his video for information on the D3 itself.

What’s nice about the D3 is the ability to run my INCOG holster with it. Since the majority of our work is from or out of a vehicle, this is a huge benefit. We don’t always have the luxury of being able to gear up ahead of time and having the ability to stuff my carry pistol directly into the D3 is awesome. This also cuts down on time as does all of these systems.

In a few of the photos in the gallery below, you’ll see my Glock 26 and a Glock 17 blue gun to give you an idea of size comparison using the INCOG. The only issue I see is moving the position of the pistol around more than two locations. I make it a point not to wear a drop down holster or carrying appendix for this reason. I work off my hip for uniform and plain clothes carry which helps with memory. The slight difference in location on the vest might not seem like much, but it is something to consider.

To quote our friends at Center Mass Group: “Professional sports teams don’t practice by just playing games, they run drills. In the sport of warfare, this is called dry-fire.” Practice, practice, practice!

Vest with Plates

CPC Plates

I’ll tell you up front I have yet to run my level IV plates in the vest on the job, so I can’t talk about its use in a real world situation. I would say that if you plan on running the plates full time that you should invest in shoulder pads. The low profile design works great with the soft armor, but adding the weight of the plates (in my case heavy CPC level IV) would get uncomfortable really quick. I have Mayflower shoulder pads on order for this very reason. I’m hoping the shoulder pads will help with my comms routing as well.

The nice thing about the Mayflower is how the plates are inserted from the outside. This cuts down on the time needed to add them to the vest. They also could be added while the vest is being worn if you have a buddy to help you.

Velocity Soft Armor


As I stated at the beginning of this article, I needed soft armor for use in a Law Enforcement role. The soft armor backers used in most plate carriers don’t give enough coverage in my opinion. The SPEAR cut is a good option and would allow them to be used in different vest platforms which is nice. This was initially the route I was looking to go, but I found it hard to find a vest that would answer all my needs.

After networking, I was assured the Velocity Cut would fit my requirements and several friends in the know told me Velocity really takes care of their customers, so I felt comfortable making an online order. I learned this first hand when the wrong vest was shipped, but they quickly resolved the issue to my satisfaction. I wouldn’t hesitate to order from Mayflower again.

I’m 6’0″ and float around 220 pounds. After a few emails about sizing, I settled on the medium sized panels. I was happy to find the Velocity panels were close to my custom fit issued PPE vest panels (see photo comparison.) I did give up some of the side overlap I’m used to, but overall I’m happy with the Velocity cut. The back panel is a bit wider at the top which is nice and doesn’t cut down on mobility.

Speed Plate

There’s no pocket for a typical front 5×8 soft armor trauma insert so if you want (or are required) to run one, you’ll have to come up with a mounting system of your own. You can run a 7×9 SPEED plate in the front and rear by using the straps inside the vest and this is the configuration I’m using right now. You just have to remove the SPEED plates if you put in your full size plates.


I wanted to mention the cummerbund configurations I’m using to hopefully answer some questions that aren’t addressed on the Mayflower website. First, the Low-Profile elastic cummerbunds need to be flipped around to get the hook and loop up front. If you’re using the vest without a hook backed panel like the D3 then this won’t matter. But otherwise you need the loop to help secure the panel to the vest. This is a tradeoff as the rear mounting of the cummerbund uses the hook to help secure it to the back. While this isn’t a huge deal and the rear panel will secure itself, it would be nice if the Low-Profile cummerbund had a double loop option.

Molly Stix

Secondly, the “Mesh Cummerbund with PALS Webbing” utilizes only four rows of MOLLE/PALS webbing. This may or may not be an issue depending on the type of accessory you’re mounting. In my case the ITS ETA Fatboy (first generation shown) hangs a bit off the bottom of the cummerbund and the ITS ETA Tallboy is too long to use comfortably. I used Molly Stix on the Fatboy which fit just right and allows it to be removed if needed.

For a radio pouch, I’m using a Blue Force Gear Ten Speed SR25 double mag pouch. My MTX 5000 fits a bit better in it than the Ten Speed M4 pouch. Again, the 4 rows of MOLLE makes the Ten Speed hang off the bottom a bit and the mounting of the Helium Whisper does not use all of the webbing as it normally would.

I just wanted to mention this, as the 6×6 plate pocket cummerbund might be a better option for some.


I want to make sure to mention the custom gear makers who are out there sewing products by hand. By “custom” I mean those out there who design, cut and sew their own items either in their living room (yes, this actually happens) or in a small shop. These are the “mom and pop shops” of the tactical industry. They either offer custom one-off items for you and me, or work with companies like Haley Strategic and ITS to design products like the D3 and ETA Trauma Kit Pouches.

While there are many shops out there doing good work, I’ll mention those whose items are on my vest system:

  • Chris at Down Range Gear offers the Chest Rig/Armor Interface Kit which really gave me the flexibility to run the top chest rig straps on the inside of my cummerbund. This is a great option and works very well for my particular setup. I highly recommend you check out Chris’ other chest rig mounting options and he’s been making “Direct to Armor” panels for years. 
  • Mike at OC Tactical designs and sews the Cat Trap Tourniquet Holder among other things. This low profile design allows me to mount a Cat Trap flat under any of the chest panels. This enables the carry of a TQ without one of the chest panels mounted. For more versatility, I’ve also run Cat Traps on my medical bags.
  • Joel at Zulu Nylon Gear worked with Bryan to design the ITS ETA Trauma Kit Pouch. Joel has been a great friend to all of us here at ITS and continues to help with great new products.
  • A special thanks to Darrin at Extreme Gear Labs for working with me during the setup of this vest system. Darrin really hooked me up with the speedy delivery of the Admin Pouch before a big mission my department was anticipating. If you need a custom product, Darrin is great to work with and delivers as promised. He also helped with me with questions I had about the MOLLE VOCR and SLAPhappy panels.

All of these individuals and the rest of the small gear industry really show how American ingenuity is alive and well today. Just like I look at items made during WWII and am amazed at American design and craftsmanship, so too will our grandchildren look at gear being made today and think the same.

    This is a great article!  Thank you for writing it!  I’m a new officer and thinking about building an active shooter response kit myself.  I think your article will help me a lot!  Thanks!

    • @Alex No problem Alex, glad to hear this might help. Going modular is the way to go.

  • SW

    May I ask a question?
    I have been looking around at body armor for civilian use. You mention in your article ” I wanted a soft armor cut that will be made 10 or 15 years from now (we’ll see if this works out.) No “custom” cuts” Can you maybe explain this as I would prefer to buy something long term that wont need to be upgraded every few years?

    Thanks SW

    • @SW Most law enforcement vests are custom fit and measured to the person wearing it. For example our agency contracts with a local “cop shop” for our body armor. We go there and they measure you and send those measurements to the manufacturer. The manufacturer cuts the soft armor and vest panels to the measurements given and ships it back to the “cop shop” where we then pick it up. Other agencies have a armor representative come to the agency and measure the officers for their vest.
      So I get a set of amor panels that are sized to me which is great for “under the shirt” wear. Things get tricky when you try to stuff those panels into a off the shelf outer vest carrier. My panels will not fit in an off the shelf military vest made for SPEAR cut armor for example.
      Even if you order your vest online from say Galls, you have to provide your measurements (which can be tricky to get correct). Military soft armor comes precut to make things easy for them to issue to the masses. The SPEAR/BALCS cut is specific to the military and comes in different sizes (M/L etc). The big difference between that and LEO armor is the shape of the soft armor.
      The Mayflower and Rogue Gunfighter vests us proprietary cut armor, meaning they are specific to their armor carriers and to the company that makes the armor.
      What I meant in the article was I needed a “pre-cut” panels I could order without having to be measured. Will Velocity/Mayflower be in business 15 years from now if I need to replace the soft armor? I hope so. On the LEO side we get issued new vests every 5 years. Now there are varying opinions on whether vests run out of life at 5 years and I say they don’t, even if they are worn 5 days a week for 5 years. I think its a liability issue with the department and they feel the cost of supplying everyone a new vest every 5 years outweighs a lawsuit by the officer or family when they find out officer so-and-so’s vest was 20 years old and the department didn’t issue him a new one.
      We shot a vest that was issued to a Deputy almost 30 years ago and it worked fine using todays ammo. If you are buying a vest for personal use that is used once in a while and stored properly in your closet, you shouldn’t worry about having to replace it every 5 years.

      I hope that helps!

    • DH072

      What a awesome idea, however and believe me I’m not complaining but the cost of the mayflower plate carrier alone is expensive. I have 13 operators that I’ve just been tasked to try and find a load out / jump out / Survelliance kit for our Narcotics / Special Missions Unit. We just spent a load of money on our entry vest at over 2 grand a piec. I looked at the option of using our regular concealment vest by point blank but the carrier. Seems to be to flimsie to support a load as shown, cuz it’s pretty dang hot in San Antonio Texas our nylon raid jackets are to dang hot and entry vest are way to bulky any other ideas or help would be greatly appreciated and again I’m digging this idea it’s on point just not sure my LT will approve purchasing or form-12 the vest. Please help !!!

    • DH072 What type of soft armor do you guys use? Sounds like you need an outer carrier that will work with your current soft panels. We were issued a PPE outer MOLLE carrier which we put our concealable panels in. It was garbage. 
      Perhaps you can use something like THIS?

    • DH072

      The carrier that you referred me to is similar to our entry vest plus or minus a few items. Our concealable is point blank as well and the carrier for that is the heat gear material it’s like the under armor under shirts or the moister wicking material so I’m not sure even if I just purchase the cummerbund from mayflower would hold up the additional gear. I guess I’m just gonna have to purchase the velocity for myself so our non tactical supervisor can see the advantage of having it for jump outs vehicle assaults and surveillance. By any chance do you know of anyone I can contact to try and T&E one before I purchase one ? Thanks again

    • Ivan H


      My response comes about 2 years late, but hey I’m gonna wing it anyway.

      I have designed a carrier system that allows you to scale up or down based on your needs. It can go from being a low-vis undershirt soft armor vest (NIJ IIIA), to being a full scale carrier with Deltoid, Groin and Neck inserts with NIJ IV rifle plates.
      The single platform can be worn as:

      1) Concealable SPEAR-cut NIJ IIIA vest
      2) NIJ IIIA vest + Magazine pouches
      3) NIJ level IV plate carrier + Magazine pouches 
      4) NIJ IIIA + NIJ level IV plates + Magazine pouches

      I’m looking for buyers, so if you’re still interested in T&E, you can drop me an email at:

       [email protected]

      P.S. – I served for 2 years in the Infantry in Southeast Asia’s jungles, and the bloody heat and humidity made me design this scalable vest.

    • DH072

      The carrier we have is the point blank c-series

    • SW

      CENTCOM_Survivor Excellent. Thank you for clearing that up. I thought I was missing something quite valuable in the off the shelf body armor market. While I have your attention, maybe you can advise me on body armor suited more to civilians? The Mayflower is real nice but I think it is over kill for me.
      Your response is appreciated again.

    • @SW CENTCOM_Survivor I don’t see any real difference between what a civilian would need/use and law enforcement. When you start getting into military applications then things change (frag ratings, full plates, etc). 
      Its all about trade offs and balances. Your perceived threat will determine what armor rating you need. Since you will not be wearing this for 8 to 12 hours you don’t have to worry as much about comfort and bulk. 
      Shop around the big armor manufactures and see whats out there. If this is something you are going to use for home protection or something along those lines I would look for a external carrier as they wont have the “tails” (used to tuck into your pants) and will normally be faster to get on. 
      Good luck!

  • Highwaystreets

    Great write up! Love the fact that you’ve built an incredibly versatile setup that has multiple looks based on what you need, great use of cash!

  • Kevin

    Great description of your tailored and flexible setups.  What’s the admin/utility pouch in the shotgun photo, with the SHERIFF placard on the front?

    • Kevin

      @Kevin Aha!  Found it!  EGL Tactical hook-backed Admin Pouch.  So low profile I didn’t see it in setup #3!

  • Celanx

    A little late to the party, but how much would a rig like that go for in he civilian world?

  • Boy Scout

    Great write up!  It sounds like we are in similar positions on the PD.  I do about 90% plain clothes work, 5% suit & tie EP work, and 5% uniform work.  What I’m seeing the need for lately is a scalable system that can be overt with all the needed pouches, but be able to quickly go covert while keeping my radio and maybe mags and/or BOK/TQ.  Trying to find a rig that fulfills all those needs and is not cost prohibitive has been hard.  You’re write up has basically been my thought process in pictures!

  • Ty

    I was issued a Mayflower/Velocity Low Profile Assault armor carrier. I’ve been looking for side swift clips (male) attachments to secure my chest rig that can secure to the Velcro pile of my cummerbunds (mine don’t have molle). Do you know anyone that may make such a product? I guess I can make them myself, but would rather just purchase if already out there.

    • J lund

      @Ty down range gear

  • Josh

    What is the camo cover you’re running on the end of your rifle? I assume it’s for mitigating heat so that you can hang onto the rifle, and if so, it’s just the sort of thing i’ve been looking for.

    Thanks for your time.

  • Eric Southland

    And still going strong! I’m absolutely stoked on this system. Thanks for re-sharing.

  • Herman Faulkingham

    Good article…..somewhere there is a cop who looked at that first picture and is going to try to put all that stuff on to one rig.

  • Pitts

    Sir, where did you purchase or how did you make the small loops that secured the ear piece wiring you ran across the vest.

  • Great resource! thanks for sharing it.

  • These loadouts are sick! Great post 😉
