    This is the perfect day hike bag. The 3 liter water bladder and the storage compartment for it is fantastic. Easily cleaned and easy to put ice into it to keep the water cold. It has plenty of storage compartments and plenty of room for all your day hike necessities. Easily holds my windbreaker/rain jacket, first aid kits, snacks, wallet, multi-tool, etc. this could easily be used on a lightweight overnighter. It fits well, straps on securely and the ventilation recess for your back is excellent. It has loops to stash your trekking poles while not needed. Overall I have absolutely no regrets or second thoughts on buying this. I highly recommend Osprey packs!

    I had a similar pack, but smaller pack for hike's to Half Dome. I discovered I needed room for food, rain gear, water filter and ample water capacity. This size works great. I almost bought a smaller Osprey 25, but now I'm glad I went bigger. The straps compact my load securely, even if I don't need the extra space. It's good to know it's there if I need it.
