Crazy-soft, smooth and stretchy cotton jersey redefined to be the greatest essential of all time.

We’ve created a fabric that mimics the classic underwear of yesteryear—only supercharged. Some say it’s the softest cotton blend they’ve ever felt, and we couldn’t agree more. Our 18-Hour Jersey gets its name from the amount of time we allow the cotton, stretch LycraⓇ and smooth modal blend to rest before we even think of sewing it. Why do we let it rest? A rested fabric won’t twist or bunch—just smooth all-day comfort and a consistent fit to match. 

Welcome to your new go-to. 18-Hour Jersey is the durable, premium basic that should be required for everyday wear. Check out the reviews on our 18-Hour Boxer Briefs or shop the full 18-Hour Jersey Collection below.

  • Cool mesh zones
