Your day hike essentials might include a rain jacket, light lunch, plenty of water, and a camera, or it might include a round of brie, bottle of red, and an apple or two. Regardless of what you deem necessary during your day hikes, the Osprey Skimmer 30 Hydration Pack will carry it all. Designed to comfortably carry up to 25 pounds, the Skimmer is well suited for day hikes, long bike rides, and big days exploring the city. A supportive framesheet and mesh lined BioStretch shoulder harness keep the pack comfortable while you'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. The skimmer is fitted with plenty of pockets including a scratch free sunglasses and electronics pocket, front organizer, and front panel stash pocket for a light layer or rain jacket, just to name a few.
