  • 100% Worth the price
Size: Large Color: White (3 Pack)
Super shirts, I bought some few years back and I had some cotton ones that needed replacement so looking at cotton and those shirts I ordered more of the latter. Great material, cool feel, don't wrinkle much, long (most under-shirts get untucked because they are short)

  • Best undershirt will not wear any other.
Size: XX-Large Color: White (3 Pack)
These are the best undershirts I have ever had. I love the feel and texture. They are very comfortable and help with sweat. I will not wear any other undershirt

  • Very Satisfied
Size: X-Large Color: White (3 Pack)
I was a little skeptical at first, but the summer heat and humidity would soak my cotton t-shirt and outer shirt in no time; even walking from the parking lot into a building, so I gave this a try. This t-shirt is the answer to that problem. It keeps me dry, cool and comfortable and never does dampness appear on my outer shirt. Machine wash, hang dry (required) but this is well worth its cost and effort. Highly recommended! I normally wear XL and the XL for this shirt is perfect. Note: This t-shirt is designed to fit very snug and close-form, but this is what enables the wicking. It is not tight or binding in the least. It actually feels as though I have on no undershirt at all. ... show more

  • Material Composition Slightly Different Than Listed
Shirt seemed to fit fine and feel fine. Haven’t worn it really yet - just tried it on. Only reason I’m writing this is because the shirt I received was 93% nylon and 7% spandex according to the label whereas this item says in multiple places that the shirt is 97% nylon and 3% spandex. Not sure if they changed the material formula or if I got a different sure than I was supposed to. I don’t think it’s particularly important as I probably wouldn’t be able to tell the difference anyway. I just thought it was weird. ... show more

  • The Ultimate Undershirt
Size: XX-Large Color: White (3 Pack)
I wish that I could know which words to type that you need to read right now to assure you that purchasing 3 t-shirts at this price is a sound decision. Not just 3 t-shirts, but shirts that almost no one will actually see you wear because they are made to be covered up by another shirt. A pity, because they look absolutely incredible contouring to your body, which is a great feature for under-clothing. Unlike a typical under shirt, which is somewhat loose, constricting, and even bulky, ATEK Men’s Stay Tucked Cooling Undershirts hug you like a super-hero costume. The extra length on the shirt tail and sleeves ensures that these thirsty garments aren't going to untuck and/or ride up. Total coverage all of the time! The longer sleeves are no problem for even athletic-cut polo shirts. You simply slide the sleeves up your arms, and they will cling faithfully to your arms, remaining properly hidden. They also require no special laundering. I will gladly buy more in other colors! ... show more

  • No More Shrinking Cotton Undershirts!
Size: Large Color: White (3 Pack)
These shirts are a bit pricey but of high quality. Frankly, I grew tired of buying 100% cotton undershirts that keep shrinking over time. Pretty soon there is no tail to tuck in! These shirts are 93% nylon and 7% spandex. They are extra long--leaving lots of stretchy fabric to securely tuck. The V-neck is also a nice feature, as it completely hides the collar of the shirt from view. The fabric is also moisture wicking--like many athletic shirts are made these days. Overall, a great product. I bought one first, and then bought three more! Oh, and the shirts come in a cool resealable bag that can be reused for many purposes. ... show more

  • Good but could be better
Size: Large Color: White (3 Pack)
Cool material that does warm up and helps to regulate body temp as the day goes on. Works great as an undershirt. Couple of issues with static generation and the sleeves being too long for comfortable use with a short sleeve outer shirt. Doesn’t shrink and holds it shape well.

  • Minimized Sweat Rings - I Just Placed 2nd Order
Size: Medium Color: White (3 Pack)
I do not write a lot of reviews. However, I was compelled to do so for these AtomasWear under shirts. Bought these a few weeks ago based on reviews that these breathe better than most tee shirts. I have tried almost every kind of under shirt, SmartWool - Haynes. My office is always hot and I spend a lot of time in meetings with my suit coat on. At times, this results in some pretty warm and wet armpits. Cotton - Wool never seemed to breathe well enough to dry out while wearing. These shirts seem to wick sweat and dry better than any others I have used while wearing. These are expensive (not like smartwool), but I just placed a second order. I am not tall (at all) but these were not too long and were only minimally larger than other brands. I run true to size and these do also. The sleeves are a but longer than some, which is fine for me, as tattoos are covered and do not show though my white work shirts. If you want to put on a “gun show” these may not be for guys that like shorter sleeves. Assuming these last and do not smell over time, I might be a customer for life. I will update this review after I really wear these. These are really comfortable and soft. I paid full price both times. ... show more
