Do you feel like Goldilocks searching through the three bears house for the hydro pack that is just right? Not too big, not so small you can’t even fit an energy bar in there, one that’s just right? Meet the Osprey Siskin 8 Men's Bike Hydro Pack. Sized right when you need to carry a spare tube, flat repair tools, and your lunch inside, plus a direct-access zip path leads to an included 2.5-liter reservoir. When you’re off the bike the front of the pack features a LidLock attachment point for a standard-size helmet, and side compression straps that expand to fit a full face. An Atilon foam framesheet and Biostretch Harness allow you to keep a dynamic body movement going while evenly distributing the weight across the entire backpanel, And naturally this has an Airscape mesh covered deep ridge foam center air channel to maximize ventilation while keeping the load in close to your body. It’s the pack that’s just right for those fast escapes and Sunday rides, not too big, not too small, with room for what you need while you’re out there on the trail.
