We built the new Corner Store Musette to live in the Sim Loader line because it serves as a great supplement to some primary bike luggage- but shines outside of our bike lives as well. It's simple, durable, highly weather resistant, compact and easy to include in a larger bag as a walkabout. With enough space for a water bottle, a light layer, a couple magazines, a compact camera, etc... it's a great bag to grab for a primary walkabout bag or a pouch to pedal across town with.
