I love everything sea to summit builds. It’s always efficient, intentional, and hits all the spots when traveling and hitting the outdoors.I love the burly zippers, the fact that I can throw liquids in here without worry, and the square shape fits perfectly in my Cotopaxi bag compartments. Some Dopp kits are awkwardly shaped creating weird gaps in my travel bag- but these nestle nicely.

Keeps the elements, dirt, dust, and grime out to keep your conents safe & clean. While not submersible, it keeps your contents clean & dry from melting snow, falling rain, splashing mud, paddle spray, and fish flopping around the boat. As a size reference, the medium fits a six pack of cans with space left on the end. The zippers are shielded and have nothing to snag on. The material cleans easy with just a wet rag and returns to looking like new. One size is not enough; you'll want multiples of each size for packing flexibility while keeping your things safe & dry regardless of where your adventure takes you!

These cubes are ok for indoor use, but definitely too thin and frail for any outdoor activity that requires durability and toughness. I purchased them for a motorcycle trip but anticipate they would not have survived. Other Sea To Summit products I’ve purchased, such as the collapsible cooking set are high quality and have performed exceptionally well, which is why I thought these cubes would work. Hopefully I can exchange them for something more substantial.
