The world’s first sock with biodegradable fabrics, Lorpen Inferno Biowarmer socks are made from Sensil BioCare fabric and PrimaloftBio filling. Lorpen T3+ Inferno Biowarmer Socks are incredibly warm, designed for use on high cold mountains and in arctic conditions. Sensil BioCare is also used in the seams, but in the form of a yarn. The cuff is made of chlorine-free wool. During its useful life, the crew sock version aids in reducing the wearer’s discomfort in extreme cold conditions, both during activity and at rest. And because it is biodegradable, it will never become litter at the end of its useful life.
