Lorpen Biowarmer Crew T3+

Biowarmer socks, made from Sensil Biocare fleece, are the warmest socks from Spanish brand Lorpen. With a blend of 13% RWS Merino wool (chlorine-free) and 13% Primaloft Bio under the foot and on the toes, they provide insulation against the cold and regulate temperature throughout your activity. They are designed for the most extreme cold conditions: Arctic expeditions, high altitude. They are very comfortable to wear and come up to mid-calf.

The anatomy of the feet is respected and there is a right sock and a left sock in order to have the largest possible insulating surface area at the toes.

These socks are biodegradable.
