Designed specifically for commuters, this amazing backpack boasts a 2 - layer welded waterproof design. It sits lower than regular backpacks, effectively reducing blind spots. A shoulder - strap mounted cell phone holder is included for easy access. The wide padded straps ensure a more even distribution of the load. There's a quick - access side pocket that can hold a mini - U lock. The 2 - layer waterproof design consists of an outer ballistic nylon layer that's extremely durable, and a replaceable waterproof liner to keep your belongings dry even in heavy rain. An angled tab keeps safety lights facing backward while riding, and large reflective stripes enhance visibility. This unisex medium - sized backpack has a total volume of 24.5 L. It's frameless, top - loading, and has 8 compartments. It's waterproof but doesn't come with a rain cover. Dimensions are 16 x 11.5 x 8 inches.

Using this commuter backpack is a breeze. First, load your items through the top - loading access. You can keep your phone in the shoulder - strap mounted holder for easy reach. If you have a mini - U lock, place it in the quick - access side pocket. When riding, the lower position of the backpack will reduce your blind spots, and the angled tab will keep the safety lights facing the right way. For maintenance, if the waterproof liner gets damaged, you can easily replace it. Since the outer layer is made of ballistic nylon, it's quite tough, but still avoid sharp objects that could potentially damage it. Although it's waterproof, don't submerge it for a long time. When not in use, store it in a dry place to keep it in good condition.
