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 Mens Factor 2 Thermal Mid Layer Long Sleeve Tops are manufactured form soft virgin polyester single sided micro fleece with a hydrophilic treatment to aid moisture control and drying times. The in-built stretch allows base layers to be worn underneath these thermal mid layers without being restrictive.

These thermal mid layer long sleeve tops have a round neck that has been designed to stretch when placed over your head, whilst its low profile also means it is not prominent when worn under clothing. The long body length in combination with a drop back prevents any cold spots during activity. Set-in sleeves and contoured body panels provide a tailored fit that increases wicking and thermal efficiency. Thumb holes in the low profile cuff stops sleeves from riding up when extra thermal layers are added and protects your hands from the cold.

Sub Zero mens Factor 2 thermal mid layer long sleeve tops are suitable for all cold weather and winter activities including mountaineering, polar expeditions, skiing and canoeing, or under your motorbike leathers.
