The Prism should could be considered (for now) the most powerful backpack that any trekker or camper will want to have along. Aside from being something the comes with features that include being water-resistant and shock proof, the backpack also comes with a built-in 400 mAh solar charger which should ensure that your devices have a reliable recharging power source when the need arises.
The Prism was designed by Luke Mastrangelo and was made using a polycarbonate frame. The CNC cut frame originated from a 1/4″ thick Lexan, and bent into shape on a cold-steel bender. It’s entirely removable, which was a manufacturing decision to simplify the sewing process. The fabric skin is made of dual layer polyurethane-coated nylon for water-proofing and durability.
