You might think that the answer to this question is obvious. However, you are most likely going to need a water backpack when it comes to getting up and out on the ocean waves. If you are going to take a fair amount of equipment and accessories with you on your trips, for example, it makes sense to stay as well-protected as you can.
That’s why a waterproof backpack is likely to be a great purchase. The best models I’ve reviewed here will offer a good level of splash protection as well as fantastic volume, meaning that if you do want to take technology or electrical equipment with you on a boat, you should feel well-guarded.
You should always use a water backpack if you think there is ever going to be a risk of you knocking your items overboard.
The best backpacks on this list have great IP ratings, which means they should resist a fair amount of splashing and dunking. However, I wouldn’t recommend you do it too often!
