You could be more comfortable in better underwear.

Better underwear is softer with just the right amount of freedom and support. We engineered our own fabric and spent over 10,000 hours to make sure our underwear is more comfortable for you.

Introducing 18-Hour Jersey

A proprietary blend of cotton, beechwood modal, and Lycra, the fabric sits for 18 hours before it's cut - that's how long it takes for the material to naturally expand.

The result: a softer feel and a more consistent fit.
