Micro Modal V-Neck Back & Underarm Sweat Proof Undershirt

LARGE ONE PIECE WATERPROOF LAYER stops sweat from transferring to your shirt. Think of it as your never-fail backup to antiperspirant deodorant, durable enough to be washed over and over and chemical free.

ENTIRE BACK PROTECTED with a waterproof layer that stops sweat from transferring to your shirt. With the sweat proof protection starting at the collar and travelling down the entire back as well as under each arm, the back sweat undershirt has you covered.

STOP SHIRT SWEAT MARKS with Ejis waterproof undershirts that extend the life of your dress shirts by eliminating yellow stains caused by antiperspirants.

SILVER COMBATS ODOR-CAUSING BACTERIA. Silver is permanently bound to the fibers of our sweat proof undershirts, to keep you fresher for longer.

SUPER PREMIUM MICRO MODAL FABRIC is 2x softer and 50% more water-absorbent than cotton. With 5% Spandex to add stretch, it will possibly be the most comfortable men's undershirt you've ever worn.

STAYS TUCKED IN with added length. The slim fit design keeps the protective area snugly up against your armpits, and your back, so sweat doesn’t you don’t want it.

WHAT THIS UNDERSHIRT WON'T DO is make your sweat disappear. Unfortunately, we can’t stop sweat from happening. It may feel damp on your back and under your arms but sweat stains won't show on your shirt when you wear this powerful no sweat undershirt.
