Sub Zero Factor 1 Zip Turtle Unisex Base Layers
Sub Zero Factor 1 Zip Turtle Unisex Base Layers are manufactured from tubular 100% polyamide fabric that eliminates the need for side seams on standard base layer sizes. If you require petite thermal underwear for women (XS) or plus size thermal underwear (XXL+) then the fabric has to be opened out and cut from different patterns. This means that flat side seams will be present. All of our Factor 1 base layer tops have extra generous body lengths giving you a decent amount of fabric to tuck in to your trousers. This prevents lower back exposure when you bend over to tie your shoe laces or look for something in your backpack.
The shoulders are closed using flat seam stitching which eliminates chaffing when wearing a rucksack. The sleeves are constructed so they are set-in to the body of the base layer, providing a much better fit and maximising insulation and moisture transportation (wicking). The cuff on the sleeves is double thickness to provide extra protection for the wrist and to help prevent the loss of trapped warm air. The stand-up double thickness turtle neck features a 18cm / 7inch long YKK zip that finishes just under the chin.
Sub Zero Factor 1 unisex zip turtle tops are ideal base layers, suitable for all outdoor sports where extra neck protection is required. They also have the added bonus of the wearer being able to vent themselves should they overheat. These lightweight next to the skin base layers are ideal for skiing, cycling and hiking, and can be used in combination with the Sub Zero Factor 2 thermal mid layer underwear range for extra warmth in extreme conditions.

The very best
The very best thermals on the market. Extremely comfortable and dry from soaking wet to bone dry overnight hanging up inside the tent. Subzero thermals are without question my most important part of winter camping. There is nothing worse than being cold. I have used subzero thermals for over 30 years and consider them to be the very best
