Everything considered

In considering design, materials, multifunctional performance, repairability and end-of-life impact, we arrived at the name Allt—Swedish for “everything”.

Allt represents our first foray into circular product design. Built to last using 100% polyester key components and designed for easy repair, every detail reflects a commitment to longevity and circularity. At the end of its life, simply return the pack to Osprey for minimal disassembly and recycling, keeping valuable materials out of the landfill. Everything considered.

Four-Season
Function

Guided by the year-round demands of alpine environments, Allt’s proven design elements and versatile adaptations excel in any conditions—like an ergonomic AirScape™ backpanel reengineered to shed snow, and a modular external strap system that secures ice tools, skis, crampons and other mountaineering gear.

Futuristic 
Fabric

High-wear panels utilize the remarkable X-Pac RX36 fabric—manufactured by leading sailcloth producer Dimension-Polyant—an advanced mono-material bonds 100% post-consumer recycled polyester fabric to a polyester film, creating an abrasion-resistant, fully waterproof laminate with an impressive strength-to-weight ratio.

Carry 
Comfort

Sliding harness yoke technology enables precise torso length adjustments for a custom fit. Breathable, 100% recycled polyester CCubed™ foam pads the anatomically shaped backpanel, harness and hipbelt, while load lifters, a sternum strap and a streamlined, low-bulk hipbelt design provide comfortable, balanced load support for confident moves through challenging terrain.

Responsible Hardware & Trims

Buckles comprised of bio-based POM plastic made from captured agricultural methane, recyclable polyester webbing and removable hardware allow for easy repair, reuse or proper recycling through specialized streams.
