The Fitdom MD-1 is a 90 L mesh equipment duffel for snorkeling and other watersports. Its large opening makes it easier to load awkward pieces such as fins, while the ventilated body lets rinsed gear drain during the trip back from the water.
The listed configuration has reinforced panels and separate pockets. Check the exact model's load limit and pocket construction before packing it as a complete scuba-kit carrier. A water-resistant pocket is not the same as a waterproof phone case, especially when it's surrounded by dripping equipment.
Measure your longest fins and think about the loaded carry, not just the empty volume. A bag that fits everything still needs to be manageable for the walk to the boat. Protect your mask and regulator separately, rinse the bag after saltwater use and spread the contents out to dry. FGSS favors capacity you can use comfortably over oversized packing claims.
