Tough and organized, the Gregory Tallac 18 Backpacking Backpack is ready for all your multi-sport adventures. This pack features an offset zipper that allows wide open panel access to the main compartment where an interior mesh organizer with key clip, second padded compartment with pockets, and insulated hydration reservoir / laptop sleeve lay wait. On the outside a hydration port and sleeve keep fluids tidy, while a tuck-away waistbelt sports a pocket for quick-grabbing Must haves.
