  • Description & Key Features

When you need to look your best in a suit and tie, wear a sweat proof cotton crew neck undershirt from Ejis. Our powerful sweat stain prevention capabilities and odor crushing technology will leave your dress shirts bone dry and leave you smelling great.

Stop throwing out perfectly good dress shirts because of ugly yellow stains caused by antiperspirants. Your days of being “the sweaty guy” are now behind you.

How is the sweat proof cotton shirt different from the micro modal undershirt?

To keep you looking dry we used micro modal in the pad to deliver the same sweat absorbing and blocking performance as our full micro modal sweat blocking undershirts and paired it with lightweight, premium 100% combed cotton for the body of the shirt.

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.

What does sweat proof mean?

Our sweat proof cotton clothing is engineered to prevent sweat stains. Can we stop you from sweating? Heck no! But we can keep sweat marks from appearing on the armpit of your dress shirts.

What if it doesn’t work?

You get a full 45 days from purchase to put your first undershirt to the test to make sure it really works for you just like it does for tens of thousands of other men. If you feel it’s not right for you just let us know and we’ll give you a refund.

Do sweat proof cotton shirts shrink?

Cotton shrinks because the heat from the washer and dryer release the tension applied to the yarn during the manufacturing process. Like most cotton clothing, a cotton sweat proof shirt will shrink if not washed correctly. To avoid shrinkage, follow our cotton shirt care instructions.

Does cotton absorb sweat?

Cotton is a versatile, lightweight, economical material – perfect for undershirts and t-shirts. Cotton is a sweat-absorbing fabric, too, which is why ordinary cotton t-shirts are a nightmare if you sweat heavily. Ordinary t-shirts leave sweat next to the skin and they’re notorious for embarrassing sweat stains. Ejis added our super-absorbent micro modal underarm pads to give our sweat proof cotton undershirts serious sweat-fighting power. You get all the benefits of cotton with the added confidence of our anti-sweat stain technology.

    Great product

    These shirts are great and comfortable to wear took a few days to get use to it does not completely protect from sweat from coming through there is a little leaking after wearing it for 8 hours but it is definitely worth the money

    Hi Nathan, Thank you for sharing your experience! While the thickness takes some getting used to, most customers stop noticing the sweat proof layer after wearing it for 30 minutes or so. I am so happy to hear that your Ejis undershirt is worth the money! Have a great day, Merrielle Ejis Customer Support
