Made without seams from super-soft Body fabric, the Men's Zonal III Base Layer Set is a joy to wear. Both parts are form-fitting and loaded with stretch for comfort. The high-wicking fabric helps to regulate your core temperature by keeping you cool when you're sweating and warm when your cold. They dry quickly once wet (ideal for longer trips when you might need to wash them) and have anti-bacterial odour control built in. Perfectly suited to every kind of sport.
