I was looking for a small bag I could use to commute to work. I ride my bike and take he bus to work on any given day. This pack is awesome! When I commute by bike I am able to get a pair of jeans, a t-shirt, ball hat and essential cycling tools (including a spare tube) into it. With the waist strap utilized, the pack stays put on my back. When I use the transit system instead of my bike, I do not need to carry much stuff so the waist strap can be hidden for a clean look. The cell phone holder in the strap is a bonus feature that I love.
Thanks Back Country and Patagonia! A definite fan here!
