Factor 2

These thermal mid layers are manufactured from open width (roll) fabric and are produced using cut and sew techniques. These are designed marginally larger than our thermal base layers so they can be either worn next to the skin or over a base layer - they still want to be worn snugly otherwise any trapped hot air will be wafted out when moving.

Sub Zero Factor 2 Mens Thermal Mid Layer Leggings (with fly) are manufactured form soft virgin polyester single sided micro fleece with a hydrophilic treatment to aid moisture control and drying times.

These thermal mid layer leggings have a high rise back to help prevent any cold spots during activity and to provide extra kidney protection. The low profile covered elasticated waist band reduces midriff bulk when combined with other base layers, whilst the double fabric fly pouch opening gives extra thermal protection to the front. To reduce the possibility of friction around the ankles, the leg cuffs have been manufactured with a low profile finish.

Sub Zero mens Factor 2 thermal mid layer leggings are perfect for low and extreme cold temperatures such as found on Arctic expeditions and winter mountaineering, or when the lower body is idle for a period of time such as during canoeing, fishing or when on your motorbike.
