Sub Zero 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.

Suitable for all cold weather and winter activities including mountaineering, polar expeditions, skiing and canoeing, or under your motorbike leathers.
