Ultralight Backpack

A backpack designed in the Frameless Ultralight Hauler tradition, with an eye for multi-sport application.

Multi-day backpacking, mountaineering, canyoneering, packrafting. Sometimes, a single route may require multi discipline skills and gear to traverse it. This backpack aims to get you covered in such routes, or during single skill set adventures.

Super light, yet tough thanks to the selection of different fabrics for different parts of the pack. Plenty of compression cords and straps to manage loads during long approaches and exits, and specific features to handle the technical sections like gear and haul loops, external bag for packraft or wetsuit, special fabric at the bottom for abrasion during pack hauls and downclimbs, and drainage ports.

For canyoneering centric users and guides, we offer a Guide Edition pack.
The Guide Edition offers extra drainage ports, a technical section closure system based on two daisy chains, a higher haul loop, and two external gear loops that hold technical gear and serve as lateral handles to drag the pack through narrow canyon sections.
