The Arctic -40 is perfect for single-digit (F) cold, especially when you know conditions will not only be frigid, but damp too. Brrrrrr!


All the details of our Arctic Series sleeping bags are aimed at optimizing body temperature through cold nights. It's built with high tech Omnitherm®HL insulation using shingled construction to increase loft when you pull the top up. Draft tubes behind the full-length zipper and around shoulders keep cold from sneaking in, except if you open it up to vent excess heat out. It is incredibly durable and lightweight, and its right and left zippers allow you to zip two sleeping bags together. The ergonomically shaped foot is lined with fleece to insure toasty toes.


  • Temperature range: 14°F down to -40°F (-10°C down to -40°C)

  • Anatomical hood with draw-cord seal
  • Draft tube insulates behind zipper
