The Norrøna trademark for insulation fleece products from 300 to 400gm/m2
These fleeces are among the best long-lasting fleeces on the market. Their open structures are perfect for layering on cold days, as they trap warm air without holding condensation. When used alone, the fabrics are open enough to allow air to circulate, making you feel comfortable in milder conditions. After three years of hard use, they work as well as day one.
