Frostline Hat

Built for hard winter conditions — mountaineering, ski approaches, or bitter cold backcountry work — the Frostline is our pick when temps drop and wind picks up. A Pertex Shield shell blocks wind and moisture while the Posh Pile fleece lining delivers real warmth fast. The zip-out face mask and fold-down earflaps let you dial protection to the conditions.

• Pertex Shield 2L 30D ripstop nylon shell sheds wind and moisture without trapping heat
• Posh Pile 100% polyester fleece lining provides immediate, packable warmth against your skin
• Zip-out fleece face mask adds full face coverage when conditions demand it
• Convertible earflaps with hook-and-loop closure adjust on the fly without removing gloves
• Internal cinch-cord and foam-stiffened brim deliver a secure, structured fit in high-output conditions
