I was a little dubious at first, having purchased other products making similar claims, but any doubts I had about the efficacy of sweatshield undershirts were immediately cast aside. Suffering from hyperhidrosis (excessive sweating), the sweatshield product did exactly what it advertises, and absorbs unsightly sweat at the point of source, stopping them from appearing on any outer layers during stressful or hot occasions. I have a few of them now. Can't recommend highly enough.
As the manufacturer states, this is the only hyperhidrosis undershirt with sweat-proof back. It is highly effective in preventing sweat from seeping through your dress shirt, allowing you to maintain crisp and neat appearance even in the tropical climate.
Must buys for anyone who wants to save their dress shirts from inevitable sweat stains.
Son suffers from hyperhidrosis that mostly affects his back. He wore the shirt under his dress shirt for a wedding and it worked great! He was able to take his suit jacket off while dancing and his dress shirt wasn’t soaked!
Great shirt!!!! 100% satisfied. I am a heavy sweater. These shirts keep my uniform shirts and regular shirts dry. I can confidently wear something other than black now. If you are in doubt, don’t be, buy these shirts, THEY WORK GREAT!!!!
Honestly it works exactly as advertised, zero marks whatsoever and I rip through shirts. I am a medical student and this saves me serious embarrassment
The undershirts are amazing! So comfortable and don’t feel any sweat at all
I was sceptical at first but it was a good investment and will be buying more soon. I just wish they came in black for all of their shirts, but it's no biggie.
This product works perfect. I work in the sun with Funerals and my back would sweat uncontrollably and my suit would be soaked by half way through a service. Thanks to this product no wet suits anymore.
I work outside all day & am always embarrassed by having my shirts drenched in visible sweat. These shirts have really helped me feel more confident. Thank U & I highly recommend these shirts !!!

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.
