Released this month by Sub Zero is a new range of windproof thermal head gear. The Factor 4 range is manufactured from the same fabric as Sub Zeros award winning soft shell jackets. The soft fleece inner fabric traps warm air, insulating your head, whilst the windproof outer fabric greatly reduces wind chill. A further benefit of the fabric is that it is waterproof so these beanie hats and head bands will be showerproof (the seams are not watertight so they will leak after prolonged heavy downpours).
Currently these Factor 4 products are only available in black but more designs and colours will be introduced further on in to the year.
