Technical crew neck undershirt, made with Neat™ Fabric to keep sweat hidden, featuring a fitted construction to tuck comfortably under the dress shirts and polos you normally sweat through. 

Features a special triple layer underarm panel to fully block any moisture in the highest sweat areas.  The laminated panel looks and feels just like the rest of the shirt, yet still blocks any moisture from penetrating through.

Designed solely as an undershirt- will block sweat from passing through like a champ, but may "look" wet even if completely dry because white is transparent. So wear it as a sweat-blocking layer underneath something, or if you decide to wear it as a stand-alone tee know it will not hide sweat for the reason above.

It's normal to sweat as we move about our lives. We see that as a sign of progress.
The clothes we wear just need to keep up. 

Sweat bullets:

    • Blend of fabric and technology
    • Sweat-hiding from the inside out
    • 95% Premium Cotton \ 5% Spandex 
    • Tumble dries without shrinking

Great undershirt

Great undershirt though the armpit area still leaks sweat.

These are great. Just like their shirts. Just keep in mind that since they are undershirts the size will be slightly smaller.

Hyperhidrosis - Mid Body Sweat Lifesaver

I had ets surgery years ago which caused compensatory sweating in the truck of my body. In the summer it is extreme and very difficult in the Arizona summers. In my line of work I meet a lot of people and have to dress business causal daily. There is nothing more embarrassing than meeting a client with sweat seeping out areas of my shirts. I was looking for a nice undershirt that absorbed sweat through the whole shirt area not just underarm areas like most shirts. To my surprise this shirt works EXACTLY as advertised. Yes if you sweat a lot you can still feel it under the shirt but no sweat escaped to the outside of the undershirt as well as no sweat was visible on my outer shirt. I have tried all the "sweat" protector shirts out there and this is the only one I have found that gave me full protection all over my upper body not just certain areas. Highly highly recommend even if your sweating is not as extreme as mine.

These are decent undershirts. They do feel heavier than the Dri-fit material I was using before. It also feels like I sweat more, but they do hide most of the sweat. I still have a little show through my work shirt at my waist and shoulders. Overall, still better than the full soak through I used to deal with.

As advertised

I purchased the Neat crew and v-neck undershirts is size M (6'2, 185), use the v-necks under button up shirts for work and the crew necks for the gym, basketball, and most recently skiing. While I do not generally sweat through cotton undershirts, I much prefer the fitted feel and vastly superior moisture wicking of Neat. The v-neck fit is particularly notable if you wear tailored or slim fit shirts. The crew necks are perfect for mitigating sweat pooling during all of the above sports. I also wear the crews when lugging around my daughter in those front or back baby carriers. Neat has replaced my DriFit shirts for winter sports, as Neat keeps me warmer / drier pre and post exertion.
