The Menâ€™s 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, resulting in garments that breathe better than pure merino, wicks 3 times faster, and feel 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 odour 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.
