I bought this pack to replace an old one. This has to be the most comfortable pack I have worn in years. The zipper pouches are perfect size to hold my hiking food. Water bag is good size and not too heavy when full, you'll have to weigh your own bag depending on how full you fill it. I also carry a katadine water filter. Worth the money! Gorgeous colors too...It keeps your water cold a long time with just the insulation it has. Ive put the water bladder, a couple bottle waters, a tackle box, a telescopic fishing pole, and action cam gear with room for a little bit more stuff. The only negative i can give it is that the helmet attachment might not work with all helmets. Works best with slimmer or smaller helmets. For under $25 is a good deal for meJust as described. Great price and lots of storage.Loved the way it was packed, and the water bladder is a plus. Lots of pockets.Bought it for my kidHe love itFor tbe price is a awesome dealBuy itI bought the teal one. It is super easy to refill, the nozzle is easier for me to pull water through than others I've sampled from family hikers. There is room for trail mix, keys, phone, bear spray etc without weighing me down too much. Per experienced hikers' advice: do not empty after use or add anything to keep mold away - it's not needed ; refill it & keep full after each use; USE FILTERED WATER.It is light, strong, and roomy. Ideal for day hiking.Lots of space
