Sauna Kind Hat

Longer time spent in the sauna has been linked to greater health benefits in large, long-term studies. A landmark 2015 study published in JAMA Internal Medicine following over 2,300 adults for 20 years found that longer sauna duration was associated with significantly lower risk of fatal cardiovascular disease and all-cause mortality. Follow-up research published in 2018 in Mayo Clinic Proceedings showed that higher total weekly sauna exposure was linked to improved cardiovascular outcomes and reduced risk of sudden cardiac death. These benefits are thought to come from sustained heat exposure, which increases circulation, heart rate, and vascular function- producing effects similar to moderate exercise.

Yes. It's designed as one-size-fits-all and stretches comfortably to fit head sizes 54-62cm (21-24 inches), which covers 95% of adults. The merino wool has natural elasticity so it molds to your head without feeling tight.

Not at all. We use premium 18.5-micron Australian merino wool, which is incredibly soft - nothing like the scratchy wool jumpers you might remember or other synthetic/standard wool sauna hats on the market.

It's tested and proven up to 100°C (212°F), which covers traditional saunas, infrared, and steam rooms. The merino wool actually performs better at higher temperatures - it's designed for serious heat.

That hat still works well. The hat sits comfortably over long hair (bun, ponytail, or loose). Many users with long hair actually prefer it because it keeps hair contained and protected from heat damage.

If looked after, years. We've designed it for 500+ sessions minimum. The seamless one-piece construction means there's no stitching to fail, and premium merino wool is naturally durable.

Absolutely. Direct heat on a bare scalp is intense and uncomfortable. The hat provides a protective barrier that makes sessions far more tolerable and lets you stay in much longer.

After each session, simply shake out excess moisture and hang to air dry in a well-ventilated space. Merino's natural properties mean it resists odour, so you'll only need to wash it occasionally. When washing, use cool water and mild detergent and hand wash, then reshape and lay upright to dry.

Yes, it works perfectly in both. Whether you're at 60°C in an infrared or pushing 90°C+ in a traditional Finnish sauna, the merino wool regulates temperature the same way. We've tested it extensively in both.
