Key Features

  • Ultralight Jacket Hood with No Cords or Toggles

    It moves with you, while fitting comfortably snug around your face like the hood on a jacket

  • Zipperless Arm Ports

    Ready for instant use, our arm ports have no zippers, toggles or hook-and-loop closures to get in the way

  • Garment-Style Shoulder Design

    When you’re upright in the bag, our tapered design rests on your shoulders—not your head

  • Centrally Placed, Ventable Zipper

    The 58" zipper is easier and more natural to operate. Dual sliders can be zipped from the bottom for venting

  • Draft-Prevention

    The draft collar, tube, and curtains keep warm in and cold out

  • Stowable Footbox

    Foot box can be tucked up with toggles to prevent the bag from dragging when you walk around

  • Don't Fear the Wet

    DriDown stays drier, keeps warmer, and dries faster
