Next generation sauna hat
The Sauna Hat
A sauna hat protects your head from extreme heat — but most look ridiculous, itch like mad, and stink after one use.
Valk is the next generation sauna hat: engineered from liquid silicone, Merino wool, and copper thread to regulate scalp temperature, block odor, and outlast 30+ wash cycles.
Stay longer. Stay cooler.
No burns. No smell.

Why Most Sauna Hats Fail
Typical wool sauna hats are tourist props — not performance tools. They trap heat, deform after washing, and scream “novelty merch.”
Valk was built by Heat Shock Labs to solve every one of those complaints through precision materials and measurable performance.
