Exactly what I was looking for without breaking the bank. I needed a hydration hiking pack that could hold more than my previous camelback. This one is awesome! I can hold thinner hoodie/jacked, my wallet, keys, sunscreen, first aid kit, a couple smaller books, an extra water bottle, and some snack space. I used this hiking around Arches and Canyonlands in Utah, and it was fantastic. I also use it when mountain biking. The chest and waist straps are great and the bag is very comfortable to me.I haven't used the bladder yet, because my old 3 L camelback bladder is still good, so I stored it in case my current one breaks. Looks decent enough though. I can't comment on the plastic taste some mention.I think this pack will last a long time, and I couldn't be happier with the price. It has a "thinner feel" that my previous camelback, but it's way less expensive, and I still feel the quality of the stitching and fabric is awesome.
