CamelBak M.U.L.E. Hydration Backpack for Mountain Biking - 100 oz Water Reservoir, Magnetic Tube Trap & Easy Refill - Perfect for Hiking, Cycling & Outdoor Adventures

Thickness?? Why is that a review criterion?Firstly: my previous generation M.U.L.E. was stolen. i didn’t like this one at first. but it’s grown on me. like a benign cyst. I wish it had more external connections, but otherwise holds everything i need. in cute little compartments. recommend some waterproof bags to carry wallet phone keys, multi tool. I wish it carried more water. i drink a lot of water.Secondly: no secondly.
