A Place for Everything

Designed with real-world hiking in mind, the Stratos 34 keeps trail essentials organized without sacrificing access. The spacious main cavity, combined with a dedicated bottom compartment and front stash pocket, means you can separate sleep gear, extra layers, and daily necessities efficiently. The hipbelt pockets and stretch side pouches ensure water, snacks, and small devices stay within arm’s reach while you navigate switchbacks or scramble along exposed ridgelines.

AirSpeed™ Suspension

The Stratos 34 uses an innovative AirSpeed suspension featuring a LightWire perimeter frame and a mesh-trampoline backpanel. The result is lightweight support, enhanced airflow, and a comfortable, stable ride even when you’re fully loaded. If you’re a hiker who values cooling comfort during hot ascents or long days, this design makes a noticeable difference in how you recover between climbs.

Raincover Included

Be trail-ready in all conditions. The built-in raincover is stored in a dedicated bottom pocket, ensuring you can protect your gear from rain squalls or sudden weather changes without slowing you down.

Bluesign® PRODUCT

The Stratos 34 carries bluesign® PRODUCT accreditation, reflecting a commitment to responsible materials and production. That means focused attention to environmental standards and social responsibility in the components and process behind the pack you wear on the trail.

Who It's For

Ideal for day hikers who push for longer miles, alpine explorers carrying a bit more gear, and anyone who prioritizes airflow and organization on mid-length trips. If you value a balanced blend of quick-access pockets, a dedicated bottom compartment, and a breathable backpanel, the Stratos 34 is crafted to meet those needs without compromise.

Practical Tips for Getting the Most Out of Your Stratos 34

• Use the bottom compartment for a compact sleeping pad or light sleep system to keep costly items separate and easy to reach on overnight stops during long routes.
• Load heavier items closer to the back panel and center of gravity to maintain stability on uneven terrain.
• Take advantage of the Stow-on-the-Go attachment to reduce gear management interruptions when moving at a rapid pace.
• Route your hydration hose through the internal sleeve and Hydraclip to minimize snagging and keep it tidy during long climbs.
