Mountain Duffel 40L

Took this on a four-day trip and the 40L size fit everything without feeling bulky. The water-resistant lining came in handy when my water bottle leaked, and the top valuables pocket kept my passport dry and easy to grab at security.

The removable backpack straps saved me on a long airport walk, way better than carrying it by the padded handles the whole time. The water-resistant lining came in handy when my water bottle leaked inside, nothing else got soaked.

Took this on a rainy weekend trip and the water-resistant lining kept my clothes completely dry when my water bottle leaked. The top valuables pocket is where I stash my keys and wallet, and the key clip means I'm not digging around at the bottom anymore.
