Built with tough 840-denier nylon tarpaulin fabric coated with thermoplastic polyurethane (TPU), water simply cannot penetrate the Filson Dry Backpack. The advantages of using a nylon fabric with this coating rather than polyester or canvas are lightness of weight, flexibility and abrasion resistance. The highly-flexible TPU coating is resistant to ultraviolet light and chemicals, ensuring durability and longevity without breakdown from hard use. The seams are radio-frequency (RF) welded, a cement-free process that permanently fuses the fabric layers together, assuring flexible integrity without fail. All webbing and padding is securely stitched to an additional layer of the waterproof fabric, which is then RF-welded to the bag’s body. This is the same construction as used in the manufacture of white-water rafting gear, where equipment failure could have fatal consequences.
Not only is the Filson Dry Backpack built to industrial standards, it’s thoughtfully designed in Filson’s Seattle headquarters for comfort and maximum functionality. The breathable back panel is padded with high-density EVA foam for carrying comfort, and the adjustable, padded shoulder straps are anatomically-curved to match the shape of your body. Added D-rings to the shoulder straps for convenient attachment of a GPS, whistles or other gear that requires instant access on the trail. With a sternum strap that’s adjustable for position and width, the load will be secure with no concern about straps slipping off your shoulders. The top closure is a reliable and time-proven roll-top design. With the top rolled down three turns and snugly buckled with the side-cinch straps, water cannot enter the bag. This closure design also affords the ability to compress the bag for varying load sizes. For added convenience, the front sports a zippered expandable-mesh pocket and the interior a mesh zipper-security pocket.
The Filson Dry Backpack – fully-waterproof protection and load-carrying comfort that’s engineered for the wettest conditions, for the long haul.
