This backpack was clearly engineered with riders in mind. The overall design is lightweight, and the airflow back system kept me cool. The Elements also has many reflective strips on the straps and across the back. Dainese claims the bag is 100 percent waterproof, but inside the exterior pocket a label screams, "!Unable to render embedded object: File (Warning) not found.! Zippered Pocket Is Not Waterproof." Prolonged exposure to rain is okay, Dainese explained, but the zipper may leak if it is submerged under water. Buyer beware.
