Mesh bags are made out of mesh material, which allows the water to escape. Carry-on sized bags can be used as cabin luggage. Waterproof bags can be used to keep the water out, but also to keep your gear from leaking in, for instance, your car.
You can fit a complete dive kit in a bag from 70L and upwards, depending on the thickness of your suit. In NL/BE you will probably need a 90L bag to fit all your gear in. In a bag which is 120L or larger, you will be able to fit 2 dive sets.
