The women’s Sphere Long Sleeve Hood is the perfect lightweight summer sweatshirt for unexpected temperature dips. This incredibly breathable and comfortable hoody is made of 135gm Cool-Lite jersey fabric. This unique and sustainable fabric blend features merino wool and natural Tencel with the addition of corespun fibers for durability. Icebreaker's Corespun fabric utilizes nylon threads wrapped in merino wool for increased strength that maintains its next-to-skin softness. The result is a top that’s warm, odor-resistance, and drapes beautifully.
