Designed for the rugged, ever-changing terrain of Japan—where hikers face rocky ridgelines, steep climbs, ladders, and chains—this ultralight frame pack adapts to your every move with a flexible, X-shaped carbon frame that delivers exceptional comfort and responsiveness, even under heavy loads.

Crafted with our exclusive Pertex®-co-developed fabric, this pack blends supple 70D and tough 210D fibers exactly where they're needed. For high-stress zones like pockets, we use Technoforce® Steel—an ultra-durable 100% UHMWPE fabric that shrugs off abrasion without adding weight.

With five back lengths and four hipbelt sizes, you can dial in a custom fit. Fine-tune load distribution for stability on long treks and technical terrain—this is our flagship pack, built for serious distance.
