RUPUMPACK Insulated Hydration Backpack Pack with BPA Free 2L Water Bladder - Keeps Liquid Cool up to 4 Hours, Prefect Outdoor Gear for Hiking, Running, Cycling, Camping, Skiing, 15L

Great hiking addition

Disappointed. This bag was not comfortable and it felt cheap. I tried it on empty and with a 5lb weight and it just felt awkward. The hip straps were pretty useless for supporting the bag and the pockets in them were too small. I didnt try out the bladder because I knew I'd be returning this. But if I'd never worn a really good hiking backpack before, I might not think this one was so uncomfortable honestly. So it's not bad, it just doesn't work for me and if you're looking for something that can carry a real load and be comfortable this is not for you.
