Norrona Falketind Warmwool2 Stretch wool-mix Zip Hood fleece is made for all-year mountaineering but works perfectly for general outdoor activities ranging from trekking to ski touring. Norrona uses the warmwool2 stretch fabric in this product because of the wool's natural thermal and anti odor properties, the durability, low weight, and moisture-wicking performances of polyester and the stretch properties of elastane. The premium warmwool2 fabric weighs between 200 and 300 grams/m2 and consists of 76% recycled polyester/18% wool and 6% elastane mix. The unique construction traps warm air without stopping moisture transport. When used alone, it's open enough to allow air to circulate, making you feel comfortable in both mild and cold conditions. Key features include: A functional hood, two mid-mounted pockets that won't interfere with shoulder straps and hip belt, a chest pocket, comfy cuffs, and a clean, snug collar. The jacket has a regular fit with a Y-cut and articulated arms for good movement while climbing.
