What Is the Best Fully Waterproof Backpack?

The best fully waterproof backpack is one built to keep water out in the conditions you expect, with a waterproof body, sealed seams, and a closure designed to block water rather than merely repel rain. For kayaking or a wet boat deck, look for a dry-bag-style pack with a properly secured roll-top or waterproof zipper; for commuting in rain, a waterproof pack may be enough without a submersion rating.

“Water-resistant” and “water-repellent” are not the same as fully waterproof: they can help in light rain but do not necessarily prevent water from entering through seams, zippers, or openings. Choose a pack with a stated level of water protection that matches your activity, especially if you plan to carry electronics near water.

A roll-top backpack can offer dependable protection when you close it according to its instructions, although accessing your gear may take longer than opening a conventional zipper. A waterproof zipper can make access easier, but its protection depends on the zipper design and whether you close it completely.

Fit matters too: choose a capacity that holds your essentials without forcing the closure open, and look for shoulder straps that sit comfortably when the pack is loaded. If you carry a laptop, account for the computer’s actual dimensions and the space needed around it, not just its advertised screen size.

Our Waterproof Large Capacity Travel Backpack for Men is an 18-inch laptop travel bag in our travel gear collection, making it an option to consider when you need room for a larger laptop. Its title identifies it as waterproof, but that alone does not establish whether it is suitable for submersion or a particular water activity.

For help planning your load, read our 18-inch laptop backpack fit and packing guide. Our team recommends considering your trip, laptop dimensions, and the protection your belongings need before choosing a bag.

Close every waterproof opening as directed, and place especially sensitive items in a separate waterproof pouch for an extra layer of protection. Keep sharp objects away from the bag’s lining, since punctures or worn areas can compromise its ability to keep water out.

After a wet trip, empty the pack and let it dry before storing it; clean it according to its care instructions. Inspect closures and seams regularly, and avoid relying on a damaged bag to protect valuables in heavy rain or around open water.
