Review on Star Water Bottle Carrier Urban by Marco Maurer

Sturdy, insulated (pleasant surprise) and beautiful. The small side pocket is big enough for a snack bar and a few packs of gum, and there's also a small mesh pocket with a stretchy top for small items (keys or a Zippo, maybe cleaning supplies). Zippers are reliable, lightweight and don't bind. I attached mine to my backpack with molle straps, so I don't know how comfortable the shoulder strap is, but personally I assume anything with a 1" strap isn't going to be good for all day use. .
