We designed the Overlook Merino Wool Liner Beanie with a low-profile silhouette for all-day comfort whether you're wearing it alone or under a helmet or hood. Made of a soft, skin-friendly blend of 65% merino wool and 35% recycled polyester that regulates temperature across a wide range of conditions, it resists odor and stays warm even when damp. The double-layered jersey-knit design provides a relaxed fit and easy-going comfort, and it's Fair Trade Certified sewn, which means the people who made it earned a premium for their labor.
