Whenever I think of the Timbuk2 I think of custom messenger bags. Actually, the word “bulky” comes to mind. So when I saw they had a Daypack, I became interested. The Undergournd Day Pack is well designed and has easy access flaps and all the custom pockets you could want. You still can’t build your own like with their messenger bags and totes, but in the future I guess they will have that as an option.
