Two Fabric Choices

18-Hour Jersey & AIRKNITx

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.

  • 18-Hour Jersey is the softest underwear you’ve ever worn.

  • AIRKNITx is lightweight, breathable, and keeps you fresh all day long.

Try On Guarantee

If you don't love the first pair of underwear, we'll send you a different pair, or issue you a full refund - no return required.

You could be more comfortable.
