FZN stands for Five Zero Nine, not frozen, and that’s exactly how you’ll feel in the 509 FZN Merino Hoodie. The low-profile balaclava hood fully sealing out the biting wind, while the built in facemask tucks away inside the collar until you need it. Naturally breathable, fast-drying, and odor-repellent, comparing this base layer shirt to grandpa’s wool knickers is like upgrading your sled from his 1978 Panther to a PRO-RMK.
• Balaclava hood fitted for use under a helmet
• Covert Collar - tucked away in collar when not needed, or pull out for full face coverage
