Power Wool™ Skull Cap

ultralight and packable thermoregulation

Made of soft Polartec® Power Wool™, which uniquely isolates plush merino wool on the inside, and a high-stretch technical knit on the outside. This harnesses the natural thermoregulating powers of wool while dramatically improving its resilience.

• smooth and flexible design interfaces under a helmet, or conforms over a cap or balaclava
• high-stretch fit engineered to be comfortable on all head sizes and stay on at high speeds with or without goggles
• accommodates various positioning options for coverage, ventilation and personal expression
• created to span everything from high-output aerobic activity in cold conditions, to mild conditions, and casual wear
• exceptionally durable and easy to care for, with natural odor resistance
• no other wool fabric comes close to its total comfort and long-lasting performance

Merino wool’s marvelous isothermic properties derive from the dramatic temperature variation the sheep endure in Australia and New Zealand. This enables headwear that has a warming effect when it’s cold, yet is also pleasantly cooling when it’s warm.
