Product Details

The Original, and Still Our Best Seller.

Sweatshield Undershirts started with the classic V-Neck undershirt, and we're still making them more than 10 years later.

Our V-Neck undershirt with an impenetrable sweat-proof barrier in the underarm is the best shirt in the world for keeping sweat from showing through to your dress shirt, your polo, or your casual wear, whether you're making a presentation, going on a date, or just spending time with your family. Our technology stops sweat marks and keeps you cool, comfortable, and confident the entire day. These look and feel like a premium brand, and you can wear them knowing that you'll feel and look dry all day.

  • Luxurious micro modal fabric, which is 50% more absorbent than cotton, ensures that perspiration doesn't end up as sweat marks. This works on the entire shirt, not just the underarms.

  • Keep-cool technology provides comfortable temperature control all day with lightweight, breathable material that still keeps moisture controlled. No sweaty cotton!

  • No deodorant stains or sweat stains means that your outer shirts last longer. You'll save money on and stop stressing about the shirts you show the world.

  • Classic V-Neck styling for use with polo shirts, t-shirts, casual shirts and business shirts when you want to wear them unbuttoned.

  • Tailored, stay-tucked styling keeps the shirts laying flat and the neck looking crisp, avoids bunching, and is tagless.

    I've been wearing these shirts for some time. I wear a suit for work and am always hot, even in winter. With the undershirts I feel confident and relaxed. This means less stress. Perfect.

    Best undershirt for problems you'll find

    I'm not so bad with arms but back is a pain, however this product is fantastic for all. It does everything I could ask for and life has changed drastically since. If you suffer from any of these embarrassing issues I can't recommend it highly enough.

    Yes - they work

    Very pleased with the purchace, the undershirts are a snug slim fitting which I like and the natural colour does'nt show under a pale shirt. It definitely stops your work shirts getting damp under-arm so you can stay smart in the office without worrying about sweat-rings or odour. Washed & worn a couple of times now - all good so far.


    Been suffering from lack of confidence due to sweatmarks, to the point where I'd only wear black in order to cover it up. However, my life has drastically improved since purchasing these and I'm super impressed - very highly recommended! Thank you!

    The best and only solution to my sweaty armpit

    For years and years I have suffered a lot of embarrassment due to sweaty armpits. I have tried everything, antiperspirants you can think of, useed lemon and even tried to use Aluminium Chloride prescribed by my Gp. Still didnÍt work.
    I tried sweatshirt and itÍs just like a miracle. The whole day I didnÍt see any visible sweat mark on my shirt
    I bought 8 more..3 whit, 3 black and 2 skin tone .
    IÍll be ordering more soon .
    Highly recommended

    confidence after all those years

    After years of not being able to remove my jacket, all has changed! And confidence that there wonÍt be any underarm stains leads to more general confidence. A real life-changing product. They do wrinkle under your shirt but that is a small price to pay in my view.

    Changed my life!

    I can't tell you what these t shirts have done for me, I have the confidence to wear whatever I like now and know I won't have horrible sweat marks!
    I got the the value 5pack and will be getting another 5 shirts soon!

    Keeps your armpits dry!

    These undershirts really do their work! We live in Italy and my husband has to drive a lot to various meetings always wearing shirts, plus he tends to sweat a lot. First time he wore Sweatshield he noticed a major difference with a standard cotton undershirt. The underarm pads seem quite thick and heavy when you see the product, but don't feel so at all, on the contrary, they really make you feel comfortable and dry. The only recommendation to the manufacturer we have is: please make the undershirts that also absorb extra sweat on the back! It could be another brilliant solution for the people who spend hours in a car seat! Thank you!

    From sweat patches to no antiperspirant

    I'm someone who would get under arm sweat patches during on a couch on a cold day. I would never raise my arm over head. Wearing these undershirts, I'm super confident that no one can see any under arm sweat. I still check my outer t-shirts at the end of the day to see if I have visible sweat patches and I'm still in disbelief that my outer wear is dry. The only two negatives I can draw are that the sleeves are a bit too long for a few of my T-shirts and that as I'm wearing more layers I'm a bit warmer than normal. Not that you'd be able to tell, you can't see me sweat! I'm starting to just wear cologne without antiperspirant as well some days, as I know I have no chance of sweating through the undershirt. I will be buying these again.

    Choose V Neck for use with polo shirts, t-shirts, casual shirts and business shirts when you want to wear them open collared (unbuttoned).

    Choose Crew Neck for a sharp undershirt neckline with an open collared shirt. If wearing a buttoned up collar with a tie then crew neck will make the undershirt neckline less visible.
