Fleece socks utilising the revolutionary PrimaLoft® ACTIVE insulating fabric. With minimal pack size and weight, they can be easily stowed until the overnight. Designed to be used in a lightweight sleep system to boost warmth and retain heat at the extremities, not the daily commute. Minimal seam construction keeps weight low and reduces rub points whilst the PointZero sole unit increases moisture resistance and the silicon logo detailing provides grip on the groundsheet. PrimaLoft® ACTIVE blurs the line between traditional insulation and fabric. PrimaLoft® ACTIVE loosely weaves PrimaLoft®’s industry-leading insulating fibres through a fine polyester mesh. The resultant structure is warmer and less than half the weight of a conventional fleece product – Down-like performance when dry whilst also still performing when wet. Designed for use in a tent or sleep system only, not for active use.
