Last year at Interbike the boys at
Holdfast were kind enough to give me one of their then pre production samples of their
Daypack. Since then both B. and I have been using it frequently, and recently they were kind enough to send over one of the production version so now we both have our own. (cute)
While it's not the bag I use for commuting or my everyday life, it has become the go-to for trips to the dogpark, to the beach, running, or just day-tripping. It holds all the stuff I need, and nothing else and it's super lightweight and moves well while running and jumping.
At $85 and made in the U.S.A. I can't recommend one enough.
