I bought this pack for mountain biking and used it for a few rides, but ended up going a different route for my gear. The pack is in great shape shape, there’s no rips, tears, or anything. Clean reservoir and added bite valve guard. Here’s the description from Osprey: Designed for discerning mountain bikers looking for a do-it-all pack, the 8-liter Siskin provides a stable, breathable and highly-comfortable carry. A next-gen reservoir provides plenty of hydration for your biggest rides and features like a separate main compartment and LidLock helmet carrier give it all-day versatility.
