The concept that takes breathable back systems to the next level. Your state-of-the-art breathable jacket won't be breathe if your backpack gets in the way. Most current 'breathable back' solutions employ a suspended mesh, but be warned - only 43% of a typical mesh back is actually breathable. 57% is in fact the surface area of the mesh. The ultimate answer? Lowe Alpine's new Pure Air Zone® back system. Entirely removing the need for mesh, this breakthrough design gives massive ventilation through minimal back contact, yet retaining excellent load stability. An advance so significant that the performance of your Lowe Alpine GORE-TEX® outerwear will be maximized. Lowe Alpine Pure Air Zone® - the difference is clear. Technology Menu
