Protect Your Fertility in the Sauna
High heat doesn’t just lower sperm count. It can stress your whole hormone system. The impact can start after one sauna and may take months to bounce back. And it can restart every time you go.
You don’t have to quit the sauna. You just need to stop going in unprotected. Our cooling shorts help shield your vital area from heat, so you can keep the benefits without the extra risk.

Breathable, Clean Comfort
You’re sitting in 200°F/93°C heat. Your pores are open. The last thing you want is synthetic fabric on your skin.
That’s why we use 100% premium cotton for breathability and comfort. It also helps hold the cooling pouch in place, close to your body, so it doesn’t sag or shift during your session.
