Items in the collection come featuring Nike Sphere technology which provides warmth without unnecessary weight. The innovative fabric uses a 3-D structure to create space between the body and the garment, where air can be held and warmed by the body’s own natural heat. The fabric’s structure also allows moisture to escape, helping to maintain excellent breath-ability.
The Spring 2013 Collection comes with three different options featuring Nike Sphere technology for men: Nike Sphere Bomber Jacket, Nike Sphere Hilf-Zip and Nike Sphere Hoodie.
