Be More Comfortable in a Better Undershirt

Wouldn't you like an undershirt that stays tucked, doesn't bunch up, and generally feels great? We did, so we made one. Our undershirts are designed with a longer cut, slimmer fit, and softer fabric—our signature 18-Hour Jersey.

18-Hour Jersey

Our proprietary blend of cotton, smooth modal, and stretch Lycra®, this fabric sits for 18 hours before it’s cut. That’s how long it takes to naturally expand. The result is a softer feel and more consistent fit.

Feel It to Believe It

Try it on. If you don’t love it, let us know, and we’ll help you find the right fit. Returns are always free.
