Review on Stay Hydrated on the Go: KBNI Hydration Backpack with 2L Water Bladder for Outdoor Activities - Running, Hiking, Camping, Skiing, Cycling by James Pope

Overall I really like it and I think it's good value for money. Remember that the chest strap is very short and the waist strap is moderately short. So, while I'm fine with that (I'm 5ft 2in and about 125lbs), someone with a larger bust and waist doesn't need these straps. I was able to adjust the chest strap about an inch and a half more and the waist strap allowed me to adjust about 10 inches more. I'm not sure if I can wear belts when wearing winter clothes. The material looks high quality. The front pocket is big enough. for a cell phone in a pocket. There is plenty of room in the backpack for a few small items like snacks, wallet, bug spray etc. I like the overall small size and convenience of this backpack for day hikes when I don't need a lot of extra gear.
