The stuff inside a backpack weighs enough without the bag itself weighing things down. Filson's Surveyor 25L swaps out the brand's signature Tin Cloth and Rugged Twill for dry-waxed Cordura nylon, retaining water and abrasion resistance without adding weight. The exterior has a zippered front gear pocket and padded back panel, while the polyester ripstop-lined interior offers stow and padded laptop pockets. Finished with YKK zippers, lightly padded adjustable shoulder straps, and a sternum strap for load distribution.
