The Osprey Skimmer 30 Hydration Pack will carry it all. Designed to comfortably carry up to 25 pounds, the Skimmer boasts a supportive frame sheet and mesh-lined BioStretch shoulder harness to keep the pack comfortable while we're on the move, and the included 2. 5-liter hydration reservoir makes it easy to stay hydrated during those hot and sunny days on the trail.
