This is an awesome bag. First of all, it carries 3 litres of whatever liquid you want. The material used is non staining and doesn't hold the taste of the liquid either. Another good thing is that when i fill it up with ice and water at the beginning of the day, 8 hours later, the water is still cold. It's got one main compartment that's large enough to carry your harness, and draws and slings, and maybe a sandwhich or two. It also has a little accesory compartment that's good for headlamps, keys, knives, and the such. I'd say the price is great for the bag, but i got mine for $30 on a pro deal, so you can't beat that. Great bag.
