Evolution is nature's reflex to ensure dominance in demanding environments. The Breeze changed it all in 2004 and a decade later, it's only gotten more breathable, lighter, and more durable. Perfectly suited for an effort beyond what you thought ''possible''. Whether that's faster or farther is up to you. So whatever you decide, a GORE-TEX liner and an exclusive Vibram Contact sole free you to focus on the hike of your life.
