If you live in a stormy area and have to carry a laptop, iPad, or important documents back and forth from work everyday, the Aquapac stormproof messenger back certainly is a solution to keeping everything waterproof and safe. And in a rather stylish manner as well. In addition to be light, strong and waterproof, the bag also comes with an removable laptop sleeve that can hold a 15.7 inch laptop for extra protection that can slip right in and out of the bag. The bag also is very comfortable to carry with padding in both the shoulder strap and where the bag hits the back. Keep those files safe.
