Extra Long to Stay Tucked In

Added length and stretch ensures it stays tucked in all day.


How does the technology work?

The Ejis sweat proof technology acts like a barrier between your sweat and your clothes, leaving you looking drier. The silver embedded in the fibers fight odor causing bacteria so you smell good all day. It won’t make your sweat disappear (we’re still working on that). So it may feel a little damp but it won’t show on your clothes.

What if it doesn’t work?

You get a full 45 days from purchase to put your first unit 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.

Does it protect everywhere?

The sweat proof technology is concentrated on the areas that sweat the most, under the arms and the back for the undershirts and across the butt, crotch and back of the legs for the boxer briefs.

What if it doesn’t fit me?

Your first undershirt and/or boxer briefs are covered by our First Product Guarantee. If you don’t love it we’ll help you find the right fit.

Ejis: Sweat Proof Undershirts and Boxer Briefs for Men.

Ejis’s premium undershirts — crew neck, v-neck and deep v-neck — provide the luxury, comfort, and ultra-softness that can’t be duplicated in men’s undershirts. The key is in the fabric: Ejis premium sweat proof undershirts for men are made of 95% Micro Modal and 5% Spandex and use anti-odor technology to create a comfortable, slim-fit undershirt that you can wear under any shirt. Ejis offers sweatproof underarm undershirts, the perfect option to replace your basic undershirt because they keep you dry by trapping underarm sweat and reducing odor. The Ejis underarm and back sweat proof undershirts offer even more sweat protection leaving your clothes dry and you confident. The sweat proof boxer briefs for men are made from the same premium fabric as the sweat proof undershirts and offer sweat and odor protection in the butt, back of legs and groin.
