What Our Gearhead(R) Experts Are Saying:"I've taken the Freerider Pro 30L+10 SL on everything from short tours to multi-day missions and it's hands-down one of the most versatile ski packs I've used. The expandable volume is a game changer for hut trips, and I love how the snow-shedding back panel keeps gear dry. The dedicated compartments keep avy gear, goggles, and helmet secure and easy to access."When we're chasing powder stashes deep in the backcountry or stringing together hut-to-hut routes, the Deuter Freerider Pro 30L+10 SL Backpack keeps us organized, balanced, and moving efficiently. Its SL fit is dialed for a narrower frame, and its sleek shape and expandable volume make it ideal for both quick-hit dawn patrols and longer multi-day tours. We count on the Lite System and flexible Delrin(R) U-frame to comfortably support our load without adding bulk. Thoughtful touches like a fleece-lined goggle pocket, helmet holder, diagonal and side ski carry options, and a separate avalanche gear compartment make this pack fully featured for demanding tours. Plus, it's built with recycled materials and bluesign(R) approved fabrics, making it a sustainable pick for big mountain missions.
