  • Features

    • Insulated bladder compartment with easy in/out bladder attachment helps keep fluids cool or warm on long runs (can fit up to a 3-liter reservoir; sold separately)
    • High-density polyethylene frame increases load capacity and can be removed for light-and-fast endeavors; hip-leveraged suspension enhances stability
    • Patent-pending sternum buckle system keeps the pack secure during upper body movement; it uses shock cord with stretch for unrestricted breathing and rebound for a stable ride
    • Light, durable, silicone- and polyurethane-coated nylon fabric resists water, abrasion and tears, standing up to a wide variety of rough-and-tumble forays on- and off-trail
    • Light and strong XT mesh wicks moisture away from your skin so it can evaporate quickly, helping you stay cool and dry; sweatproof webbing won't absorb moisture
    • Zigzag stitching over elastic adds durability and stretch; safety-stitched bar-tack reinforcements at all stress points
    • Plush-feeling microfiber polyester edges are soft and non-abrasive against skin and clothing
    • Quick stash pockets keep gear organized and easy to reach; adjustable drawstring cords help secure items in the front pockets
    • Rapid access pocket with magnetic closure allows quick access to chapstick or other small essentials
    • Quiet, bounce-free zipper pulls are easy to see and use
