Concealment Labs Concealment Liner Review: My Favorite Way to Conceal Carry in Athletic Clothing

I wear athletic clothing most of the time, and I prefer carrying inside the waistband. Because of that, I'm always looking for products that let me comfortably conceal carry regardless of what I'm wearing.

Recently, I've been testing the Concealment Labs Concealment Liner, and after spending some time with it, I think it's one of the best solutions currently available.


Overview

The Concealment Liner is a fairly simple system built around a rigid Tegris frame. It's available in two sizes:

  • Flex - 8.5 inches wide

  • Mini - 6.5 inches wide

On each side of the frame is a proprietary buckle secured with two bolts. Instead of a traditional rigid connection, Concealment Labs incorporates shock cord into both ends of the frame.

The idea is to allow a small amount of stretch without requiring you to constantly adjust the belt. As you sit down, bend over, or even after eating, the shock cord allows the system to flex slightly while maintaining support.

The buckles are also adjustable, allowing you to change their angle and cant. That's something you don't commonly see on products like this, and it helps the belt conform better to your body instead of forcing everyone into the same geometry.

The belt itself uses webbing that feels very similar to a car seat belt. It's smooth, flexible, and surprisingly comfortable.


How It Works

Using the Concealment Liner is straightforward. You can either loosen the belt enough to step into it or wrap it around your waist and buckle it. Once it's in place, simply clip your holster directly onto the Tegris frame.

Because the system supports the weight of your firearm independently from your clothing, you can comfortably carry in almost any type of bottoms, whether they have belt loops or not.


Why It's Become My Favorite

I've tried quite a few concealed carry systems designed for athletic clothing. Most of them work reasonably well, but they all feel like different takes on the same basic concept. The Concealment Liner stands out in several important ways.

It Actually Stays Put
This is probably the biggest reason I've grown to like it. With other belt systems I've used, repeated draw and reholster drills gradually cause the belt to ride upward and loosen. Eventually I have to stop training and readjust everything. That hasn't happened with the Concealment Liner.

Oddly enough, the belt material is actually quite smooth, like a seat belt, so I expected it to shift even more. Instead, it has remained securely in place throughout my dry fire sessions. I'm sure there's eventually a point where enough repetitions would cause it to move, but I simply haven't reached that point yet. For my training, it has stayed exactly where I put it.

It's Extremely Comfortable
Because the Concealment Liner stays put on its own, it doesn't require extra accessories like the leg leash found on the Phlster Enigma. Likewise, it doesn't rely on clips like the Leisure Carry Clip-On Belt. The result is a thinner, simpler setup that reduces bulk while also helping minimize printing. Out of every athletic carry solution I've tried, this has easily been the most comfortable.


It's Not Perfect

Even though it's become my favorite system, there are still a few things I'd like to see improved.

The buckle works, but it's not particularly quick to use.
Personally, I don't want to loosen the belt enough to step into it every time, nor do I enjoy completely undoing the belt whenever I put it on or take it off. A quick-release buckle would make a huge difference here and would immediately improve the overall user experience.

The Shock Cord Makes Tightening Harder.
I actually like the idea of incorporating shock cord into the design. The problem is that it's used on both sides of the frame. Whenever I tighten the belt, part of my effort goes into stretching the shock cord instead of tightening the belt itself. Personally, I think the adjustment side should be rigid while leaving the opposite side elastic. That would preserve the flexibility during movement while making it much easier to achieve a tighter fit.

Long-Term Durability

Another question I have concerns the longevity of the shock cord. I'm stretching it multiple times every day, and eventually elastic wears out. Time will tell how durable it is, but I'd like to see Concealment Labs offer replacement buckles or rebuild kits if the cords eventually need servicing.

Loosening the Belt

The adjustment mechanism is also a little cumbersome when loosening the belt. Concealment Labs demonstrates loosening it with a single finger, and while that's technically possible with slack in the belt, I haven't found that to be the case once it's fully tightened.

When the belt is under tension, I usually need both hands. I first have to relieve pressure on the shock cord before I can move the buckle's locking bar and loosen the belt. It's definitely the slowest adjustment system I've personally used.


What I'd Like to See

If I could make one suggestion, it would be to borrow a few ideas from the Phlster Enigma. I've been using an Enigma for nearly four years, and its Fidlock magnetic buckle remains my favorite belt closure system. The quick-release mechanism is incredibly fast, and more importantly, I can loosen the belt with one finger regardless of how tight it's adjusted. Combining that style of buckle with everything else the Concealment Liner already does well would make this system extremely difficult to beat.


Final Thoughts

Even with those complaints, I'd still choose the Concealment Liner over the other athletic carry systems I own on most days.

There are certainly situations where something like the Phlster Enigma still makes sense, but for general concealed carry in gym shorts, joggers, sweatpants, or other athletic clothing, the Concealment Liner has become my preferred option.

It stays in place, it's exceptionally comfortable, and it allows me to carry inside the waistband without relying on whatever clothing I'm wearing.

Overall, I think Concealment Labs has built one of the best concealed carry solutions for athletic apparel currently available, and it's a product I can confidently recommend.

Votatu PMD504-R Budget Red Dot

I was recently sent the Votatu PMD504-R red dot for review. 

It features an aluminum housing, side brightness adjustments, and utilizes the RMR footprint. 

This optic is powered by a side-loading CR1632 battery and allows you to choose between 3 reticle options: dot, circle, or circle dot. 

Overall, this is an optic that has some comparable specs to many others in the market, but a major selling point is definitely the price point, considering that you can get it for a bit over $100 dollars.

I’m going to be mounting this to my FAB Defense AMP Pro SL build and will test it out on the range soon, so we’ll see how it fares.

Osight XE AMRS Red Dot

This is the new Osight XE, an enclosed red dot that utilizes the RMR footprint. 

It features a multi reticle system that lets you cycle between 6 reticles, notably allowing the choice between a 2 MOA and 6 MOA dot. 

This optic also features a collapsible backup rear sight that pops up when the button on the left side of the XE is pressed. 

You may have noticed that this optic looks a lot like the Osight XR and that’s because it’s basically the same thing. However, the XR utilizes a built in battery that is recharged via the included magnetic charging cover, which itself is charged via USB-C. The XR is a good optic but a common request is for it to just use a normal interchangeable battery system and this is where the XE comes in. It ditches the rechargeable battery for a side loading battery tray and is powered by a CR battery. 

The Osight XR has been working well over the past few months and I can only assume that the XE will perform just as well considering that again, it’s basically the same optic as the XR. I’ll be testing the XE more and will come back with a more in depth review.

Alpha 6 Defense A6 Vapor Micro Compensator for Glock 19 Review: A Budget Alternative to the Radian Ramjet?

Personally, I prefer ported and compensated handguns. If you've followed my content for a while, you've probably seen the Radian Ramjet and Afterburner come up more than once. It's my favorite compensator setup because it works well and looks great. There really isn't much to dislike about it other than the price. Depending on the sale, you're typically looking at anywhere from $350 to over $400. Even though I like the product, it still hurts every time I have to buy another one.

That led me to start looking for alternatives, which is how I came across the Alpha 6 Defense Vapor.

Design

Like the Radian Ramjet and Afterburner, the Vapor uses a proprietary barrel and compensator system. Instead of a threaded barrel, the barrel features a proprietary front lug that mates with a matching micro-compensator, making it legal in all 50 states. The version I purchased is designed for the Glock 19 Gen 3 platform.

From an appearance standpoint, the barrel features machined flutes along its length and additional milling around the chamber hood. The compensator itself is fairly compact, and as far as I can tell, it's only available in black.

One interesting aspect of the Vapor is its mounting system. The compensator consists of two separate pieces that clamp around the front of the barrel and are secured with two screws. Of the currently available 50-state compliant compensators, I'd probably say this is the least elegant design. It certainly works, but it's more time-consuming and fiddly than competing systems.

The manufacturer also recommends applying thread locker to the mounting screws. That's another step you don't have to deal with on products like the Ramjet. It also means every time you remove the compensator, you'll likely be cleaning and reapplying thread locker before reinstalling it.

To see what would happen, I intentionally skipped the thread locker during my first range session. After a couple of hundred rounds, both screws had started backing out, so I definitely recommend following the instructions and using thread locker with this setup.

Is It Really a Compensator?

Looking at the design, I'm honestly not even sure I'd classify the Vapor as a true compensator. To me, it’s designed much more like a ported barrel.

There are already several extended ported barrels on the market that use a very similar concept. The AimSurplus JTT barrel and Lakeline ported barrel both extend beyond the slide and vent gas through a port near the muzzle. The Vapor essentially adds a clamped housing around that port.

I'm certainly not an engineer, but I have a hard time believing that this additional housing dramatically changes performance compared to those extended ported barrels. Likewise, I can't imagine it performing as well as a dedicated compensator like the Radian Ramjet and Afterburner.

Unfortunately, I don't own a Gen 3-compatible Ramjet, so I can't perform a direct side-by-side comparison.

Alpha 6 Defense also doesn't provide much technical information about the Vapor. Their product page contains fairly generic marketing language without much detail explaining how or why this design is supposed to outperform other options.

Strange Lack of Information

One thing that immediately stood out to me was just how little information exists about this product.

After searching online, I found only a single YouTube video featuring the Vapor, and it was the manufacturer's own installation video from a couple of years ago. Since the product launched in September 2023, there haven’t been any independent reviews.

I found one Reddit post mentioning it, but none of the people involved had actually tested the product. Even Alpha 6 Defense's Instagram only featured a handful of posts before going quiet after April 2024, with several of the comments simply asking whether the Vapor was reliable.

From a marketing standpoint, it's one of the stranger products I've come across.

Why I Bought It Anyway

With so little information available, I was definitely hesitant.

The main reason I bought it was because I needed a compensator for my Ruger RXM build. My RXM slide has a very blocky profile with sharp, squared-off chamfers at the nose, and I was fairly confident the Vapor would visually match those lines better than anything else on the market.

Thankfully, I was right. The fit isn't absolutely perfect, but I honestly can't think of another compensator that complements this slide better aesthetically.

Quality Control

If it weren't for how well the Vapor matched my RXM build, I probably would have returned it immediately.

The barrel I received had visible scratches, while the compensator had rough, jagged edges that looked poorly finished. It was easily the worst cosmetic quality I've seen on a brand-new barrel.

I contacted Alpha 6 Defense, and to their credit, they immediately acknowledged that it shouldn't have looked that way. They offered to exchange it without any issues.

Because they handled the problem quickly, I'm not going to hold that quality control issue against them. Still, if this compensator hadn't matched my slide so well, I probably wouldn't have kept it.

UPDATE: No sign of the new Vapor to replace the damaged one I received yet, and no word from the manufacturer.

Range Performance

I was only able to test the Vapor at an indoor range, so rapid-fire testing wasn't possible because of range rules.

During testing, I experienced several malfunctions, primarily light primer strikes on the first round of a magazine.

I've never encountered this issue before, and some research suggests it can happen if the slide isn't fully returning to battery. That could potentially be related to the barrel, but it's also worth mentioning that the slide itself was brand new and had never been fired before.

At this point, I don't think it's fair to blame the Vapor until I can perform additional testing.

Outside of those malfunctions, nothing else stood out. There weren't any obvious issues that I could directly attribute to the compensator.

Accuracy was also perfectly acceptable. I shot a 20-round group at 10 yards, offhand at a moderate pace, and stayed comfortably within fist size despite it being a slightly off day for me.

Recoil Performance

Without having a Gen 3 Ramjet available for direct comparison, I can't make any absolute claims.

However, my everyday carry Shadow Systems MR920 runs a Ramjet and Afterburner, and I've put thousands of rounds through that setup. Based on that experience, I don't think the Vapor reduces recoil nearly as effectively.

To me, it behaves very similarly to a single-port barrel, which honestly makes sense considering that's essentially what the design is.

That's not to say it performs poorly. It definitely shoots softer than a standard Glock or, in my case, a factory Ruger RXM upper. But any well-designed port or compensator should accomplish that. I simply don't think it's on the same level as the Radian system.

Looking at the design, the Vapor vents gas through a single forward port rather than using a larger expansion chamber like the Afterburner. Because of that, I don't think it has the same mechanical advantage when it comes to reducing muzzle rise and felt recoil.

Value

This is where things become difficult. The Ramjet generally costs between $350 and $400 depending on sales. The Vapor has an MSRP of $375. At that price, it's an easy pass for me. I've also seen it available around $307 through Optics Planet. Even at that price, I’d still pass.

I personally bought mine directly from Alpha 6 Defense during a sale for $250 plus $10 shipping, bringing my total to $260. At that price, I felt it was worth trying, especially because it completed the overall look of my RXM build.

Even so, I still have some buyer's remorse. The Lakeline ported barrel costs around $160, while the AimSurplus JTT barrel is about $60. Based on what I've experienced, I suspect either of those options would deliver very similar recoil reduction.

Ultimately, you're paying a significant premium for the additional clamping compensator, and I'm not convinced it's doing enough to justify the extra cost.

Final Thoughts

If you're specifically trying to match the look of a blocky slide like I am, the Vapor is one of the best-looking options available. That alone was enough reason for me to buy it.

From a performance standpoint, however, I don't think it offers enough over a quality ported barrel to justify its price.

If I weren't trying to complete this specific build, I'd save the money and buy a Lakeline or AimSurplus ported barrel instead.

That's simply where I landed after spending time with the Alpha 6 Defense Vapor.

Slim Fit Holsters Carnex Review

I've been building a few different firearms lately, including a Ruger RXM paired with the Icarus Precision aluminum grip module. One challenge with that setup is holster compatibility. After researching available options, I found that only a handful of companies currently support the RXM/Icarus combination, which is how I came across Slim Fit Holsters.

After reaching out, I had the opportunity to speak with James, CEO of Slim Fit Holsters, who provided a few review samples. As always, receiving products does not influence my opinions, and Slim Fit had no input on this review prior to publication.

For this review, I'll be taking a look at the Carnex, Slim Fit's newest sidecar-style holster system.

At first glance, the Carnex appears to be a traditional sidecar holster with an attached magazine carrier. However, Slim Fit has incorporated several features that help set it apart from many competing designs.

Modular Attachment System

My configuration includes a firearm holster and spare magazine carrier, but Slim Fit offers additional attachment options including carriers for OC spray, flashlights, and knives. Compatibility will vary depending on the specific item, so it's worth contacting Slim Fit if you have questions about a particular setup.

This modularity gives users more flexibility than a typical sidecar holster that is permanently configured around a spare magazine.

Tegris Flex Hinge

The two halves of the Carnex are connected using what Slim Fit calls a Tegris Flex Hinge. In simple terms, it's a laser-cut piece of Tegris that connects the firearm and accessory carriers.

It's a straightforward design, but one that works well. Tegris provides enough rigidity to maintain structure while still allowing the holster to flex with the body. This flexibility improves comfort when carrying and helps the system conform to the wearer's shape. I've used similar Tegris-based designs from other manufacturers and have always found them comfortable for all-day carry.

Carrier Arms Attachment

One feature I haven't seen implemented quite this way by other manufacturers is Slim Fit's Carrier Arms Attachment system.

Instead of bolting accessories directly to the holster body, the Carnex uses a Kydex carrier arm that acts as a mounting interface. Combined with multiple mounting holes, this allows users to adjust both the height and angle of attached accessories.

This added adjustability can be useful when trying to optimize comfort, improve accessibility, or create additional clearance between carried items.

Another benefit is that the Carrier Arm incorporates its own concealment wing. This works alongside the concealment wing on the firearm side and the included foam wedge to help pull both sides of the system closer to the body.

Many sidecar holsters only include a concealment wing on the firearm side, despite the spare magazine often being the portion that prints the most. Adding a second wing is a thoughtful touch that should help with concealment.

Carbon Fiber Finish

Slim Fit offers a large selection of colors and patterns, as well as thicker Kydex options for users who want additional durability.

One thing that immediately stood out to me was the carbon fiber finish.

Many carbon fiber Kydex holsters I've owned show distortion after the forming process. The pattern can appear stretched or uneven, especially around tighter contours. On the Carnex, the carbon fiber pattern is consistent throughout the holster. The finish looks clean and uniform, giving it a noticeably higher-end appearance.

If aesthetics matter to you, this is a nice bonus.

Premium Hardware

Another small detail I appreciate is Slim Fit's use of aluminum washers. My holster uses black washers, but several color options are available.

Many manufacturers use plastic washers, while others use generic metal hardware. These aluminum washers are some of the nicest I've seen on a holster. It's a small detail, but when you're spending $150-$200 on a premium carry setup, those details help justify the price.

Customization Options

One area where Slim Fit stands out is the number of options available during the ordering process.

Customers can choose from different sweat guard heights, optic compatibility, compensator coverage, colors, hardware options, and other modifications.

Many manufacturers have moved toward more standardized configurations because they simplify production, but I personally appreciate having the ability to tailor a holster to my specific setup.

Final Thoughts

At this point, my impressions are still early. Most of my time with the Carnex has been spent dry firing and getting used to the design. I'll continue carrying it and putting more range time behind it before forming a long-term opinion.

That said, my initial impressions are extremely positive. The modular design, adjustability, dual concealment wings, and overall build quality have all stood out to me so far.

I already feel that I'll end up preferring the Carnex over my current Tier 1 Axis Elite. The ability to comfortably carry pepper spray alongside a firearm while maintaining good concealment is particularly appealing.

I'm looking forward to spending more time with the Carnex and seeing how it performs as an everyday carry setup.
