  • Lightweight, strong nylon ripstop shell fabric stands up to abuse without weighing down your pack during the day

  • Innovative vertical baffle system reduces weight and helps transfer heat from the core of your body to your extremities
  • Flexible baffle stitching hugs your torso and eliminates interior dead-air space that can rob you of body heat
  • Snag-free zipper tracks so you don't rip the bag fabric getting in and out
  • Collar drawcord helps eliminate draft
  • Ergonomically shaped footbox provides more space and comfort for your toes
  • Zipper draft tube keeps cold air out
