It uses a one-finger zipper that’s easily accessed on the move, an internal mesh “anti-rattle” sleeve, and reflective graphics. The top mesh compartment is perfect for stowing a phone where you can see it to run maps, play music, or just grab it quickly for photos.The Jerrycan has seen some updates of the years, and now exists in a standard wedge shape and a bent version to accommodate braces at the seat tube / top tube junction.

Logan’s Thoughts: I used the Ortlieb Cockpit-Pack on a 1,400 mile scouting trip and really came to like it. The long zipper allows you to open the bag wide, and the internal compartment is lined with hi-viz yellow to help you quickly and easily spy the stuff you want.
