Osprey Stratos 36 Hiking Backpack - Lightweight Daypack for Men & Women - Perfect for Outdoor Adventures, Camping & Travel

I used this pack for a week of day hiking through the Swiss alps, and I'm very pleased with the pack. It has plenty of storage space and compartments for a day hike (could probably be used for a light overnight weekend hike as well). The two pockets on the top of the pack (one accessible from the inside, one from the outside) are convenient for phones, keys, etc. The large main storage area is accessible from both the top and the side. There's also an external pouch on the back of the pack that's good for holding a first aid kit or other miscellaneous items. I absolutely love the trampoline-style back - it kept the pack off my shirt/skin, which made for very comfortable hiking. The strap points for trekking poles were very useful. I got caught out in the rain one day, and the built-on rain fly worked well.I only have a few minor complaints. The water bottle pockets are not easy to reach while wearing the pack. It took some contortion to reach my water bottles without taking off the pack. Of course a water bladder (the pack has a compartment for one) would have solved this. The pack will not sit upright if you place it on the ground - it will roll on its back, so be sure not to keep anything fragile in the back outer pocket. Finally, the pouches along the waist strap could be larger. They're too small to hold most cell phones, but I used them for my wallet, keys, hand sanitizer, etc.Overall this is a very good pack!
