@mike8 thanks for reaching out with this question! To make sure we're clear, it sounds like you're looking for a duffel-style bag with an external pocket that is specifically designed to hold a coffee mug (presumably that is full of liquid and therefore needs to stay upright!) - assuming that's true, here are a few tidbits:
- The majority of the duffel bags we carry are pretty streamlined on the outside of the bags, mainly to eliminate the risk of external pockets getting caught up/damaged during travel (think: baggage claim conveyor belts); in addition, because many duffels can double as backpacks, the rotation of the bag then eliminates the effectiveness of a pocket designed primarily to carry a mug in one direction
With that said, we found a few duffels you might consider, noting that they aren't designed specifically for carrying a coffee cup:
While we recognize these aren't exactly what you are looking for, we hope this helps gives you some ideas - in addition, please let us know if it would be helpful for us to suggest a few pack styles that may feel like a duffel and specifically offer the coffee mug pocket!
At REI, we believe time outside is fundamental to a life well lived.
