Buy T THOMPSON TEE Men's Sweatproof Undershirt | Slim Fit V Neck T-Shirt With Underarm Sweat Pads | Aluminum-Free Alternative, White, X-Small from Vests at desertcart.in

Review: Perfect - Fits tight enough so you can't see under a dress shirt, absorbs well - wouldn't have anything different.
Review: Excelente camiseta - Se trata de una camiseta con refuerzos en la parte de las axilas que absorbe el sudor e impide que pase a la camisa que llevas por encima. Obviamente seguirás sudando con ella puesta pero te evita que la camisa se vea sudada así como el tener que estar lavándola continuamente. El tejido es de fibra de bambú, muy elástico y transpirable, pero más caro que el de algodón. En cuanto a la talla pedí la M, que es la talla que uso normalmente, y queda perfectamente.

### ⭐⭐⭐⭐⭐ Life-changing product
*by T***M on 25 June 2017*

Bought for a full day assessment centre job interview. As recommended I purchased 1 size down from my usual tshirt size and this was the correct choice. This undershirt should be skin tight yet still comfortable which it was. I'm somebody who has always suffered from hypohydrosis. I ALWAYS take a jacket or coat with me which I use to cover up sweat, and hide my embarrassment, but this ultimately makes the problem worse. For this job interview though, I had to wear a smart office shirt without a jacket (company dress code). Within 30 minutes I would usually have underarm sweat marks and back sweat showing through the shirt as large wet patches. With this undershirt on, absolutely NOTHING!! Dry throughout the entire day! As there is no padding on the back (just underarms), I worried that my back would still be vulnerable, however the 95% bamboo material did an excellent job of absorption, not allowing any moisture to break through to my outer officewear. To emphasise, this was in the U.K. on the hottest day in over 40 years (35°c), in an office block without air conditioning, doing team-building tasks that required physical hard work. After the team-building task, all candidates were sweating profusely from the face, including me, however I was one of the few without a mark on my shirt. This allowed me to stay calm and focus on the interview, without worrying about embarrising marks I would usually have had on my shirt. I did well at the interview and this product completely improved my confidence on the day. As someone that has uncontrollable sweat on even cold days, the fact this undershirt did its job in much hotter conditions and in a stressful situation, is nothing short of a miracle! After a short while of wearing the shirt, I didn't really notice I had it on; this is also why it's important that the undershirt is not a lose fit, it should be skin tight but not uncomfortable. The shirt is unnoticebale to others looking at you, there's nothing to suggest you are wearing anything other than an office shirt by itself. If the idea of wearing formal shirts and certain colours fills you with dread, give this a try. It's expensive yes, but if you suffer from hypohydrosis, it's a small price to pay to get your confidence back. I paid for this product myself and have written this review as an unbiased reaction to my experience with the undershirt.
