Keep your top half dry and comfortable with our large selection of men's thermal tops - long sleeved or short sleeved, we have a massive choice of designs for a range of budgets.
Why wear thermal underwear?
The base layer regulates your temperature. This effect is caused by a layer of tiny fibres lying close to the skin, trapping essential body heat, regulating air flow and wicking away sweat, to keep you from getting cold, too hot, or wet.
Synthetic base layers dry quickly and are lightweight. Each brand takes a different spin on the synthetic base layer - have a look at our selection from X-Bionic, Craft, Picture Organic Clothing and more.
Merino wool base layers are becoming increasingly popular. Merino wool is naturally breathable, regulates body temperature and has antibacterial and anti UV properties. It is also exceptionally soft and is perfect for both extremely high and low temperatures. Have a look at Icebreaker base layers on Snowleader.
