The Sphere Long Sleeve Hood is made from Icebreaker's proprietary Cool-Liteâ„¢ fabric, a blend of pure merino and TENCELÂ®, a sustainable plant based fabric. Packing for a summer adventure can be an adventure in itself. You need to be ready for any weather, and before you know it, your carry-on is overstuffed and overweight. How great would it be if you had twice the use from half the clothes? Now you do. Icebreaker Cool-Liteâ„¢ breathes better than pure merino, wicks 3 times faster, and it feels exceptionally soft against the skin. Wake up in your cabana and reach for it's softness, but keep it on for that cool morning run. As your afternoon hike to the top of the volcano takes you up through different climates, the Sphere LS Hood is a great midlayer over a tee or under a shell. Because it's merino, it resists odor so you can wear it day in and day out. Casual details and a heathered fabric make this Sphere Long Sleeve Hood the one piece of clothing that you'll wear every day of that vacation, no matter what you decide to do.
