Merino wool is a favorite on the mountain, no matter the season. Primo Pants uses fine-fiber, non-itch Merino wool from South America combined with lyocell for durability and a smooth touch. A perfect first layer for skiing, which leads away moisture and keeps you warm and comfortable as activity levels shift from uphill climbs to lighter activity and breaks. Plus the wool resists bad odors, so you'll remain an appreciated companion even after many sweaty hours – or even days – on snow.
