Camelbak has great quality. I've had other hydration packs but Camelbak is the best! I bought this unit for my daughter, I had purchased a large backpack hydration unit and she wanted to try it. I thought the smaller 1.3L would work for her. She has a 20" waist (8 yrs old) and it fit! Now when we hike or bike I don't have to carry a bottle for her. The inside of the waist is super soft and has lots of storage!
overall - ok, but mine leaked which is VERY unusual for CamelBak. It's a bit bulky compared to an earlier CamelBak version called the Catalyst. Nice divided storage compartment. The older version had small velcro compartments in the waste band on either side of the buckle which were great for holding energy gels.
