  • Dual access to pack: top loading plus a horseshoe-zipper front panel opening, like a duffel, gives complete view of contents
  • With a new ''rip-and-stick'' torso adjustment, shoulder strap system easily slides on pack's frame to fit torsos of varying lengths
  • Removable top lid pocket lets you stash some essentials to bring into tent, so pack can stay outside or in vestibule
  • Zippered pocket under lid stores maps and keys, spare batteries and other small essentials
  • Front panel features an oversized zippered pocket protected with a waterproof zipper for storing often-used gear
  • EVA Soft Edge shoulder straps move seams away from you body with cushioned edges for non-binding comfort on and off the trail
  • Durable molded foam backpanel has channels for air circulation, increasing ventilation to keep your back cool and dry
  • Pre-curved waistbelt with a Delrin® hoop is designed to cradle hip bones for a more natural fit and distribution of pack weight without sagging
  • V-pull waistbelt allows you to use a natural forward pulling motion for quick, easy cinching and precise adjustment
  • Internal sleeping-bag compartment is created by a zippered divider, separating it from gear and clothes in the main compartment
  • Utilizing four buckles, the pack's streamlined compression system lets you cinch and strap down loads for jostle-free carrying
  • Concave head pod at the top of pack gives your head freedom of movement--no more staring at the ground
  • External mesh side pockets hold water bottles, energy bars and other essentials you want close at hand
  • Behind mesh pockets both sides feature zippered accessory pockets that are sized to fit gloves, hat, energy gels and more
  • Hydration-compatible design features an internal reservoir sleeve and dual exit ports for drinking tube
