    Sealock supplies wholesale waterproof backpacks in bulk to importers, distributors, and retail buyers, shipping FOB from factories in China and Vietnam. Buying backpacks in bulk is harder than buying dry bags, because a backpack has more parts that can vary batch to batch — welds, zippers, straps, foam, and a whole harness — and because a wholesale order usually spans a matrix of sizes and colours rather than one SKU. This is how to run a waterproof backpack wholesale order so consistency, cost, and compliance all hold across the container.

A waterproof backpack MOQ is not one number a sales manager chose — it is the point where several separate supplier minimums, tooling costs, and line economics all clear at once. Understanding which of those is driving the figure is what lets a buyer bring it down intelligently instead of simply asking for less.
