We’re big fans of Baggu, from their original nylon bags in great colors, to their newer leather ones (especially in metallics). But we didn’t know they also do great nylon backpacks, and they’re only $24. Our friend Jen had this one on, and the cobalt color is amazing, which unfortunately doesn’t really come through in my picture. Maybe this one here below shows it better—they also have them in neon! They hold up to 50 pounds, fold unto their own pocket, and are machine washable.
