Matthew Pizzawrote a review of Timbuk2 CoPilot Carry-On 52-108L Rolling Gear Bag on December 31, 2017
Familiarity: I returned this product before using it
I really liked this bag with the exception of one thing. The tubes that the retractable handle recess into soak up (for me) too much usable real estate inside the bag. I get that putting them on the inside makes the bag more streamlined for storage in overhead compartments and whatnot but it was something that I just couldn't get past.
Other than that the bag is great! Durability and organization are fantastic... just what you'd expect from Timbuk2.
