The Ultimate Handcrafted Sauna Hat A dramatic improvement over a traditional felt sauna-hat, our Bastu Sauna Hat is designed to protect the head during sauna sessions, perfectly insulating the scalp from the heat of the sauna, while providing breathability for terrific comfort. Thanks to its unique shape, special three-layer fabric, and carefully sewn edges, the Bastu Sauna Hat keeps your head at a normal temperature despite the heat – which significantly increases comfort. Lighter than other Sauna hats, each Bastu Sauna Hat is hand-crafted to exacting specifications in northern Sweden, and comes in a wooden box, along with a certificate of authenticity. Unisex, and machine-washable, with multiple edging colors available. Sizing: Large/Medium: 58-63cm (23-25in) Medium/Small: 53-58cm (20-23in)
