I have spent a lot of time and money finding ways to make a patrol shift in Texas more comfortable. I have tried athletic brands, brands that have slapped “Tactical” on tight fitting shirts, natural fabrics, etc. You get it. I have worn this shirt for the last couple weeks of patrol in 95+ degree days and am very satisfied.
Dissipates moisture quickly, doesn’t rub or chafe under my uniform shirt + external carrier, doesn’t wick moisture into my waistband or boxers, and doesn’t reek after peeling it all off.
Price point is steep—and I can’t speak to longevity—so I’m hoping that buy once cry once holds up. I did buy a couple to keep fresh in the laundry rotation.

TLDR: Don’t spend a bunch of money on other stuff until you at least try this. It does exactly as the sales copy says it does.

I ordered the Maxx-Dri Silver Elite short sleeve shirt to replace a polyester active wear shirt. While this polyester shirt did provide some improvement in moisture control with my Premier Body Armor T-shirt, the 221B shirt was a much better product. It is well constructed light weight and provided superior moisture control. Even 90+ degree weather I felt very comfortable wearing the Maxx-Dri shirt. When I removed my body armor at end of day there was minimal moisture, no odor and the Maxx-Dri also had minimal dampness. Great product that performs as advertised.

Impressive. This quickly became my favorite shirt. I got one in black and soon got a white one too. It's worth the price due to the versatility, breathable fabric and comfort. It seems to make any shirt you wear over it more comfortable. Especially like it under heavy wool sweater

Shirts are a bit pricey but definitely worth it. The breathability and durability is very surprising. I can’t wear these in my uniform due to the breathable holes being to noticeable but I wear these to bed or when I go out walking/jogging. Might wear them during judo next week!

This is the best base layer for the heat. Nothing better while wearing duty gear.

Love the shirts

Pairs very well with the Maxx dry vest! No more peeling my shirts off my body after shift or feeling the twisted uncomfortable of a hot, sweaty tshirt under a vest. Love it!

I wear an outer carrier vest everyday for work and without any hesitation this is the best undershirt I have ever tried. They’re super light, and thin. The collar of the neck does not get loose and it always looks sharp and in place. The shirt fits tight to the body but it does not feel like it’s suffocating you. I don’t think I can ever go back to a regular undershirt again.

I got the Level 5 vest kit. And a FREE T-SHIRT. Well thanks at $60... thats very expensive, free well i though im going to try it out...SO.. I though 4 days. Hot days. I wore it didnt wash it, tryed the odor reducing ability... I showered and hung t-shirt up it dried overnight from a sweaty day.. it was dry in the morning.
Well I'm on day 4 no stink. And still good.
Now im going to save up for a couple.. But $60 this is a lot.. ?

If you want to be comfortable when it's hot, get this shirt. Under body armor or by itself, it will keep you cool & dry. Great product!

I got these shirts several years ago when you could get them in a 3 pack for $93. $31 each and with the discount code I got them for under $85. I come today to see about getting more and they are almost double the price now. I don’t see how the price rising that much is justified but I can attest that these shorts are awesome. After several years of wearing them they hold their form and still holding strong. Now I just need a discount code so I can order more.

The shirts after a 8 hour shift holds a great amount of moisture, and after it dries I reuse it about 3 times a week.. great Quality

I'm a security guard in Southern Arizona and a ballistic vest is mandatory. I used to wear cotton t-shirts and at the end of my shift I'd be drenched in sweat, even below my duty belt, and equally stinky. Not only do these shirts keep me dry, they don't stink. I wore the same shirt four days in a row, and it STILL had no bad odor. They also stay tucked it, unlike the undershirts I previously wore. Literally one minute before writing this, I ordered two more three packs. I'm very happy with them.

It definitely is better than other cooling/moisture wicking sport shirts for civilians. After end of watch I no longer need to feel like i'm peeling cheese apart removing armor and base layer shirt. Definitely helps keeping air flow, but this isn't a miracle shirt you'll still sweet but the shirt won't feel like its glued to you after your watch. Only issue it's a bit pricy other than that works well.

I’ve been in law enforcement for just over 20 years. I have never found an under shirt that 100% fits the bill. This shirt does, from the breathable fabric to the arm pit panels that keep the seams afar from your pits I love it. Historically I would need to cut the sleeves off just to keep from getting a rash. This these shirts that is no longer a problem. My only grip is I wish they were a little cheaper in price.

I am in law enforcement and I am very picky with how the collar of the short fits around my neck. If its too loose around the neck, my shirts seem to always move around under my work uniform. My wife searched high and low and spent hundreds on name brand shirts to only be disappointed. 4 years ago she purchased the white ones. Our uniforms changed and we are now required to wear black! To my surprise they had black ones available this time around! 100% recommend this brand! And we rave about this company on local law enforcement pages!

This vest and shirt combo is amazing. Its summer time in southern California and temps are 100 degrees. This vest allows a/c air to circulate around my back and escape through my collar. The only hiccup so far is the vest rides up to my neck. I mess with it as I get more experience with it but well worth the investment.

I was skeptical at first with this purchase as other shirts I’ve purchased that were suppose to be “ordor fighting” or “odor resistant” always smelled funny out of the package or turned funky after a week of wearing them. I’m a clean person and no matter how I washed the shirts and myself both always ended up with a funk by the end of the day. It got super frustrating. A buddy turned me to 221B for the Max-Dri Vest and swore it worked so when I ordered the vest I picked up one of their shirts to go with it. Best shirt by far over any shirt I’ve tried wearing. Whether you wear an internal or external vest I think you’ll like the shirt. It breathes, is stretchy and fits nice. The only “negative” thing I will comment is (and I saw another person point it out on here checking out reviews) is it could be a tad longer on the length as I like my undershirt to be close to the same length as my uniform shirt. In the end it’s not a deal breaker for me but a little more length would make this the perfect shirt.

For reference - 6’1, 205lbs semi-athletic figure and the Large fits perfect minus the preference I stated above.

Keep up the great products 221B!

These shirts are a lifesaver in the Louisiana heat. My only complaint is I would like to see more colors. Navy, Grey, Tan, OD green would be a good start. LMK if/when new colors drop and I'll buy 3 packs of every color.

I purchased 3 of these, and they work as advertised. I am former Army and current Law Enforcement, and they work better at keeping odor at bay while wearing them under body armor. The hybrid fit is good, not as tight as a compression shirt, but not loose either. My only complaint, make them longer. I'm 6'03" and they are longer than a standard Under Armour hybrid shirt, but not as long as their tall models that are offered. Like many tall guys, I have a long torso. Other than that, great product.

Classic symptoms of wearing a ballistic vest; however, the Maxx-Dri Silver Elite T-shirts stopped the itch immediately. Still getting soaked so I will pick up the vest and a few more Ts. Thank you.

These shirts are extremely breathable and resist odors better than any others I’ve tried and I’ve tried a ton.

I ordered a maxx-dri t-shirt and it was too smsll. Customer service agreed to swap it out but the post office sent it to the wrong address. Customer service was extremely helpful and worked with me to get it all straightened out. Their customer service is like their products. Top notch !!!

My husband works armed security and this summer has been brutal. Rashes, then a skin infection, led us to the dermatologist for treatment and biopsies. I began to search for an alternative to his long-preferred compression shirts and found 221b. What a game changer!

Within days of making the change in shirts the rashes were calmed down, and the infections have stayed gone. He says he is far more comfortable, stays drier, and is very happy with the change. Thank you for making such a terrific product!

I bought 1 shirt to try out and it was good enough for me to buy 6 more. I've tried a lot of others to wear under my body armor but this brand seems to be the best I've found so far. It breathes and doesn't stink after long ass shifts. Prolly gunna buy more.

Fantastic! The customer service is always great. The shirts are comfortable and don’t have any odor after 1243, hour shifts!

I like these shirts overall, but I'll be honest... the material gets a little "scratchy" on my back under my vest.
The one thing I love about these shirts is the higher collar than other compression shirts, but the mesh design starts to irritate my back after a while.
I have some UA shirts that are softer but the collar isn't high like these, and UA lost me as a customer when they went woke in 2020 so I turned to 221B.
I'd like to see a softer material in these shirts, but other than that I like them. I have the Maxx dri vest 4.0 and 3 of these shirts. I'm considering buying a couple more because the white is starting to get dingy from sweat.
Please consider a softer material and I'll definitely buy more.
