At under a pound, the Mochilla 33 carries everything you need for a fast-and-light overnight alpine push, seamlessly transitioning from the approach to technical climbs.
Engineered for Mobility:
The pack sits high above the harness, ensuring unrestricted movement on steep, technical terrain. Its tapered silhouette keeps the load close to your core, optimizing balance and stability, while the low-profile, static shoulder straps provide flexibility and responsive comfort during every subtle shift.
Weather-Sealed Access:
A hybrid shroud and roll-top closure offers a streamlined barrier against the elements, featuring a single-pull, glove-friendly system for rapid access when it counts. Dual haul loops ensure secure hauling and smooth handling on vertical transitions.
Lightweight Versatility:
Inside, a minimalist sleeve houses a removable foam frame, providing lightweight structure when needed and doubling as a bivy pad. The sleeve is also compatible with up to a 3-liter hydration bladder to keep you fueled on the move.

The KILO Chalk Bucket is a bomb-proof vessel designed to keep your chalk exactly where you want with a secure dry bag closure. The KILO stands on its own, with a tented base, and folds securely into envelope form - creating a low profile bag with a sleek expansion.
A 4"x12" zippered pocket holds your bouldering paraphernalia, and functions as a drop pocket for moving around the gym. An aluminum G-hook secures the roll top closure, and two elastic loops hold small-medium size brushes.
Inspired by the duality of 'Clouds & Dirt' - where lofty dreams and gritty realities coexist -the 2025 KILO Chalk Bucket is a Limited Edition production crafted from two vastly different technical textiles.
