Lorpen Inferno Biowarmer T3+ socks are designed for extreme cold conditions, including high-altitude mountains and Arctic environments. They combine Sensil BioCare fabric with PrimaLoft Bio insulation to provide a high level of warmth.

Sensil BioCare is also used in the seams in yarn form, while the cuff is made from chlorine-free wool. The crew-length design helps reduce discomfort in extreme cold during both activity and rest. The materials are biodegradable, allowing the socks to biodegrade at the end of their useful life rather than remaining as long-term waste.
