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. Prefer Crew Neck? See our Crew Neck shirt

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

    So good bought a pack of 5 twice



    Absolutely amazing product. Bought for my son who has suffered from anxiety sweating for a number of years and this product has been great in helping him overcome this issue. I would thoroughly recommend this product and it has really given him a boost in confidence to get on with daily life.

    Exactly as I expected

    This is the second set I have bought. Arrived in a timely manner and I fully expect another year or so of comfortable wear


    Men's Sweat Proof Undershirt (V-Neck)


    Haven’t tested it yet but it looks good and fits well and I’m sure it’ll do the job

    They just work.

    I’ve been buying these undershirts for about 5 years now. I used to have armpit sweat stains every day, now I don’t even have to think about it. Worth every penny. They’re invisible under any shirt colour apart from white, and even then it just looks like you’re wearing a tee underneath which a lot of people wear for warmth anyway. If you’re wearing a white shirt pick the undershirt that best matches your skin tone. The good news is you’ve probably been wearing white shirts a lot to minimise the appearance of sweat stains, so now you get to wear light blue and solve both problems.

    Really really impressed.

    I was very sceptical before buying but it has surpassed my expectations. Really really good product and I’ll be buying some more very soon!

    Great products

    Excellent item, I am really pleased with the undershirts.


    After being pleased with a competitor that I couldn’t purchase from anymore, I tried these. Pricing was very competitive for a 5 pack and they are way more comfortable and wash/dry better. Very happy


    I've been wearing the undershirts for a month now and for the first time in forever I've been able to wear non-white shirts without fear of massive sweat patches. Given me access to my wardrobe again, it's great.

    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.
