I love this bag. I use it every day. Commuting to work, riding to the bar before Critical Mass, riding the streets of down town during CM (thank you handy dandy bottle opener right on my chest). Every day I put this bag through hell and it takes the beating like a "champ." I couldn't ask for a better quality product (and look as cool at the same time). 5 stars x 2 + 10 x 2 more.
