Frequently Asked Questions

IcedBallz is cotton underwear with a built-in pocket designed to hold a crotch-shaped ice pack. It keeps your balls cool during sauna sessions — so you get all the sauna benefits without cooking your goods.

Your testicles are outside your body for a reason — they need to be 2-4°C cooler than your core body temperature. Saunas heat them up to 38-40°C, which can impact sperm quality, testosterone production, and overall comfort. Studies show that scrotal cooling can improve sperm motility by up to 57%. IcedBallz solves this problem.

Our custom ice pack maintains effective cooling temperatures for 30-45 minutes in a typical sauna session (70-90°C). That's more than enough for a full session.

The ice pack is ergonomically shaped to fit naturally. The cotton pocket provides a soft barrier between you and the ice — you feel cool, not freezing. Most users say they forget it's there after 2 minutes.

Absolutely. While designed for sauna use, IcedBallz works great for hot tubs, post-workout recovery, or any time you want to keep things cool down there.

Every IcedBallz kit includes: 1 pair of premium cotton underwear with built-in cooling pocket + 1 reusable crotch-shaped ice pack + care instructions card. One size fits all — just freeze, slide in, and go.

Machine wash cold, tumble dry low. The cooling pocket is designed to handle regular washing. The ice pack just needs a quick rinse and back in the freezer.

One size fits all. The underwear is designed with a comfortable, stretchy fit to accommodate the ice pack pocket without feeling bulky. No need to worry about sizing.

Holding an ice pack is awkward, it moves around, and you can't relax. ChillNuts sells a sleeve that tucks into your waistband — but it shifts and doesn't stay in place. IcedBallz has a BUILT-IN pocket in the underwear itself. It stays exactly where it should, hands-free, the entire session.

Yes — 30-day money-back guarantee. If IcedBallz doesn't make your sauna sessions more comfortable, we'll give you a full refund. No questions asked.
