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.

    Awesome shirts

    These shirts are great! Just purchased new shirts to replace the last ones that I had been wearing for 8 years.

    They work!

    The shirts have a lot of padding built into the armpits, so that padding soaks up the sweat. The padding does not affect the fit of the shirt, nor make it feel weird, so that is great! The shirts fit like an Under Armour shirt, so it is designed to be form fitting. I prefer a little looser of a fit, so I’m going to order XL instead of Large next time. (Just a little sizing advice to whoever reads this review). If you like the Under Armour feel of a shirt, then their sizing is right on.

    Exceptional Shirts that save time, money and reputation!

    This product not only works as advertised, but saves a tremendous amount of money for my family and I. In the past, I would wear a traditional undershirt which would allow sweat to bleed into my dress shirt forcing me through yet another dry-cleaning cycle. With Sweatshield, no bleed-through and my dry-cleaning bills have gone down tremendously.

    Awesome product that works better than advertised!

    Great product, very happy

    Works as advertised, as good or better than competitor shirts I’ve had. I bought one size down from normal, stretchy material makes for a comfortable but slim fit that I like. Will buy 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.
