Cotton Crew Neck 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.

SILVER COMBATS ODOR CAUSING BACTERIA. Silver is permanently bound to the fibers of our anti-sweat cotton undershirt, which keeps you fresher longer. It also helps to regulate your body temperature by pulling heat away from the body when you're hot and keeping you warmer when you're cold.

SUPER PREMIUM MICRO MODAL FABRIC IN THE PAD is 2x softer and 50% more water-absorbent than cotton alone, which means our cotton sweat proof shirt has the exact same sweat blocking performance as our micro modal undershirts.

STAYS TUCKED IN with added length. The slim fit design keeps the protective area snugly up against your armpit, where it belongs. Stop settling for slopping, disheveled t-shirts under your dress shirts – upgrade to an extra-long sweat proof undershirt.

WHAT THIS UNDERSHIRT WON'T DO is make your sweat disappear. Unfortunately, we can’t stop sweat from happening. It may feel damp under your arms but sweat stains won't show on your shirt when you wear this powerful sweat proof crewneck.
