What Our Gearhead® Experts Are Saying:

"This pack balances structure and flexibility perfectly. The vacuum-formed back panel supports the load while flexing naturally with movement, and the Air Contour™ system ensures a close, stable fit. It’s the kind of pack you forget you’re wearing, even when fully loaded for a long day in the mountains."

Designed for fast-paced hikes, scrambles, and all-day pursuits, this pack blends versatility with comfort, making it an essential companion for every mountain mission.
