Ultralight Backpack


A backpack crafted in the Frameless Ultralight Hauler style, suitable for diverse sports activities.

Whether it’s multi-day trekking, mountaineering, canyoneering, or packrafting, some paths demand a range of skills and equipment. This backpack is designed to support you on such journeys or singular adventures.

It’s incredibly lightweight yet durable, thanks to the choice of materials used in various sections. Features like optional compression bungee cords, load lifters, and specialized components like gear loops and an optional extra bag for packrafts, wetsuits, rope bags or anything extra you want to carry for longer trips to enhance its functionality. For added resilience, there’s an option to upgrade to an Ultra 800 bottom. While the Ecopak material is waterproof, some water might seep through the seams, but a central grommet at the bottom ensures drainage.

For those deeply involved in canyoneering, especially guides, we present the Guide Edition pack. This version includes additional drainage ports, a unique closure system using two daisy chains, and dual external loops for technical equipment, which also act as side handles for navigating tight canyon spaces.
