Power Wool™ Skull Cap

bring-anywhere thermoregulation with tremendous utility

Soft and breathable Polartec® Power Wool™ features fine merino wool on the inside for temperature regulation and moisture management, and a stretchy exterior for resilience.

Merino wool's marvelous thermoregulating properties evolved from the dramatic temperature variation the sheep endure, making for headwear that can stand up to extreme cold without being oppressive in warmer conditions. Its unique hygroscopic structure also manages moisture more effectively than any other fiber, absorbing up to a third of its weight in moisture without feeling damp.

• stretchy, highly-adaptable and minimal design calibrated to fit all head sizes
• roomy enough to provide full ear coverage over a cap or balaclava, yet still conform to the crown of your head under a helmet
• low-profile construction tuned to move with the high-stretch material, and reinforced to last
• supple external hem keeps only merino wool next to skin and provides a barely-there feel
• incredibly compressible and ultralight (24 g), it fits within the palm of your hand
• no other wool headwear comes close to its total comfort and long-lasting performance
