Factor 1 Eco Mens Base Layer Leggings provide excellent insulation for the lower body without the bulk that comes with wearing mid layers. 

Knitted from a blend of antibacterial bamboo, super soft merino wool, recycled polyester and elastane yarns, these base layer leggings fit like a second skin thanks to the fabrics three way stretch. Not only that, this heavy knit is lightly brushed on the inner face to provide greater heat retention, with a soft handle so as not to irritate the skin when worn.

The ergonomic design of these environmentally friendly leggings is based on our award winning Factor 2 mid layer range, with flat seams to eliminate potential rubbing points, and contoured leg panels to provide a tailored fit. The high rise back helps to prevent lower back exposure during activities, with a low profile elasticated waist and flat hemmed ankle cuffs. 

These Sub Zero Eco leggings are ideal for prolonged cold weather environments and cross over in to anything from skiing through to hiking and camping.  They can be worn on their own or used in combination with the Sub Zero Factor 2 thermal mid layer range for extra warmth in extreme conditions.
