The men’s Cool-Lite Sphere is a super-light, blended merino wool top that delivers long sleeve protection and greater breathability during warm days in the alpine. It’s made from Icebreaker’s 135gm Cool-Lite™ fabric, which blends merino wool with Tencel® for stretch, and nylon for a softer next-to-skin feel that lasts. It also features corespun fabric, which are nylon wrapped in merino for improved durability and an ultra-soft feel. The Sphere crew top is ideal for warm weather travels and for sunny days in the city when long sleeve protection is desirable.
