The standard means of moving and storing dive gear is the dive bag. All of the major manufacturers make dive gear bags. These are often quite fancy, with embroidered logos, pockets inside and out, "ergonomic" handles, and even wheels. Most of these bags are very nice but really too small to hold a cold-water dive kit, and very heavy to carry around when full. These bags are also expensive, a bother to clean, and a lot less waterproof than they claim. Here's is a convenient alternative that is much cheaper:
Go to K-Mart Home Depot and spend $5 on a Rubbermaid tote box, about the size of a milk crate. This will not be big enough to hold all items - you'll have to pack your fins and BC separately - but it will hold everything else, is small enough to fit almost anywhere, and also avoids making a single excessively heavy load. The tote also will not lose small items like a milk crate will. I eventually drilled drain holes in the bottom. I now use my fancy dive bag only to carry my drysuit and its accessories. This type of tote box is the preferred container on every area dive boat I have been on.
