Men's Merino Wool Sauna Shorts

Meet the next evolution of saunawear—designed for the full contrast ritual.

These these are the ultimate sauna shorts, crafted from 100% merino wool and thoughtfully designed for both sauna and water. With a secure drawstring waistband and built-in liner, they stay comfortably in place through cold plunges, lake swims, and everything in between.

Merino wool naturally regulates temperature, wicks moisture, and dries quickly—helping your body warm back up comfortably after cold plunges without that lingering damp, chilled feeling. Unlike synthetic swim trunks, these shorts allow your skin to breathe, avoiding trapped heat in the sauna and supporting a more balanced transition between hot and cold.

Whether you're rotating between sauna, plunge, and rest, or heading straight into open water, these are made to move with you—no compromises, no plastics, just performance rooted in nature.
