Norrona sewn Powerstretch classic headband is made for general outdoor activities such as skiing, hiking, and mountaineering but is also suitable for everyday wear. It's made in a premium synthetics/wool mix because it offers excellent thermal properties and good breathability. The warmwool2 fabric is a mid-weight (289 g/m2) recycled 76% polyester/18% wool/ 6% elastane blend, which offers the best of both worlds. The lightweight polyester is durable, dries quickly, and has great moisture transport. The wool provides excellent temperature regulation, natural odor resistance and keeps you warm even when wet. The low percentage of elastane stretch allows the beanie to rest comfortably around your head. Key features include: An inside hang loop, embroidered logo artwork, and flatlock chafe-free seams. The headband has a snug fit that fits under a helmet.
