Ciieeo 2Pcs Sauna Hat Wool Felt Hats Shower Cap Bathhouse for Women Men Russian Banya Sauna Hut Supply Grey

These are great! Super comfortable and helps your hair from overheating.

These are rather cheap and thin as you would expect at the price point. They are real wool felt, they fit my big Norwegian square head and they work. I've had issues with various forest creatures eating my sauna tooks at hunting camp, so I got these cheap ones to replace the cool one a porcupine and/or pine squirrel ate. Good, cheap option for guest tooks or to feed the animals LOL.

It sure does allow for some extra sauna time. But, the sizing is just a little too small for someone with a fat head like me, so it looks extra goofy spiking up on top of my head. My wife seems amused, but I'm not so much.

So cute and works well too
