I need a good overnight/carry-on bag for travel and I really like the keepall 55 with shoulder strap. I'm just having trouble deciding between the Damier and Mono. I like the mono but I think the Damier is more durable. Which one do you all think goes with more etc? Any other thoughts on them would be appreciated, too! Thanks everyone! Sorry if the public poll offends anyone I wasn't sure what it meant (I'm new!).
