Merino wool is a favourite on the mountain, no matter the season. Primo Zip uses a fine-fibre, non-itch Merino wool from South America that is 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 odours, so you'll remain an appreciated companion even after many sweaty hours – or even days – on snow.
