I recently received a Co-Pilot, I'm still determining if I'm going to be able to make it work as my work bag. I really like it, but it might be just a tad too small. I have a Klean Kanteen 27 oz water bottle with a loop lid, it's about an inch too tall for the water bottle compartment. I feel like I should be able to get a water bottle with the same capacity (27 ounces / 800 ml) into the water bottle compartment, it just needs to be a little shorter and a little wider in diameter. Does anyone have any suggestions?
