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.
Best underarm t shirts in existence. No comparison.
Best sweat proof undershirt
Love this undershirt. Very comfy
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!
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.
I've tried a couple of different shirts like this and the Sweatshield is top notch! I definitely recommend it!
Men's Sweat Proof Undershirt (V-Neck)
Switching from Thompson Tee. Hoping for the best as Sweatshield definitely wins from a price point perspective
I discovered these shirts about 9 years ago I believe. They literally gave me confidence and allowed me to wear tshirts that weren’t black. I could not wear colors before I found them because my underarm sweat was so bad.
Men's Size Chart
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.
