  • Description & Key Features

A simple v-neck undershirt should be a staple of every man’s wardrobe. If you wear a button-up shirt without a tie, you need a v-neck to keep the undershirt out of view. And unless you enjoy sweat stains on your dress shirts, a sweat proof v-neck is an absolute essential.

We’re like most guys – we hate sweat, and we hate sweat stains. Ejis v-neck sweat proof cotton shirts are scientifically engineered to resist sweat stains.

Our white sweat proof shirt works well under most dress shirt. If you wear a lot of white dress shirts, consider our sweat proof grey v-neck; it may seem counter-intuitive, but a grey undershirt is less visible under a white button-up. And don’t forget our black sweat proof v-neck to wear with dark-colored dress shirts or as a casual weekend shirt.

How is the sweat proof cotton v-neck different from the micro modal undershirt?

To keep you looking dry we used micro modal in the underarm 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 in 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 v-neck 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.

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 v-neck shirt.

How do I prevent sweat stains on dress shirts?

Sure, we’re a little biased, but preventing sweat stains on dress shirts begins with a high-quality sweat proof undershirt. We designed our cotton sweat proof v-necks, crew necks, and deep v-necks with guys like you in mind. We've sewn a one-piece sweat proof protective layer into the armpits to keep your dress shirts looking pristine. For other ways to prevent sweat stains, check out our article about excessive sweating.

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.

Are these v-necks cut low enough to wear with a dress shirt and no tie?

You betcha! After all, why wear a v-neck if the collar is gonna poke out when you wear it under a dress shirt? We designed the sweat-proof v-neck to look great (translation: invisible) when you unbutton a few buttons.

What’s the difference between sweat-resistant shirts and sweat proof shirts?

Fabrics like polyester make a big fuss out of being “sweat resistant.” But where does all that sweat go? If you wear a “sweat resistant undershirt,” you’re not protecting your dress shirts…you’re protecting your undershirts. Our cotton sweat proof shirts feature a sweat-absorbent micro modal pad designed to trap sweat and keep it from soaking into the armpits of your dress shirts. The difference is a true sweat proof shirt that keeps your dress shirts sweat-free.
