Small Case / Pouch For X100V

Based on the OP’s criteria that Fossil duffle is huge… It would be the bag I carried into my room for a week, not out and about at my destination. If that’s what the OP wants it opens the door to a plethora of bags, packs, etc.… Domke… Think Tank… Peak Design… even my current choice for foolin around on boats, the Watershed Ococee Drybag. (I use it with a padded camera insert.) Most of them more functional and less, or at least no more, expensive than the Fossil. For Disney I’d prefer a backpack or a sling to a duffel, but I recognize there will be differing preferences. That being said, I interpreted the OPs wish to be they carry less, not more.

In the same vein, but sized more appropriately for Theme Park EDC, I pull another bag from my collection. This one is a locally crafted cotton canvas handlebar bag that can be attached to a belt or used with a shoulder strap. Mine is by Äventyr, but I suggest it more as a type than a specific choice. (Not that I don’t recommend it — it’s a great bag and I wish I had more opportunity to use it!)

Bike handlebar bag with shoulder strap. X100V is inside the main compartment.

The Äventyr has two compartments plus a rear zippered panel that conceals the handlebar/belt straps. The camera is is in the main compartment that also has three pouches that could be used for batteries, card wallet, etc.

If I was going to travel with this bag I’d consider leaving its shoulder strap behind, attaching a pair of Peak Design Anchors to the D-rings, and using a PD strap instead. Providing the option of leaving this bag in the room and slinging “just the camera” at times.
