H.A.W.G.

 

Great for backcountry rides and hikes when lots of water and lots of gear will be carried. Heavier than most CamelBak products, but the way to go if you need cargo space. Can be adjusted to about any size of person, 10 years old or 50 years old. I've used this product for 5 years now and have never had to replace it -- very durable. 5 stars.
