Questions.Answered.

What size should I get?

Go by your normal underwear size and check the size chart in the shop section. Wrong call? Size exchanges are free within 30 days on unworn briefs.

How do I use it?

Freeze both ice packs. Before you go in, slide one into the pouch at the front of the briefs. The spare rides in the cooler, so it's still cold when you swap mid-session or go back for round two.

How long does the ice pack stay cold?

Long enough for most of a typical session. On long or very hot sessions, swap in the spare from the cooler.

How do I wash them?

Take the ice pack out, machine wash cold, hang dry. Skip the dryer to keep the fit and the pouch in shape.

Where do you ship, and how fast?

US only for now. Shipping is free and orders ship within 2 business days via USPS, with tracking by email.

What's your return policy?

Free size exchanges within 30 days on unworn briefs with tags. Worn briefs can't be returned — hygiene. Anything arrives damaged, we replace it free. Full policy →
