The Haven 20 degree bag is Therm-a-Rest's newest and first sleeping bag.  The idea behind this bag is that in order to keep you warm throughout the night you need to have insulation that has loft.  When you sleep in your sleeping bag, however, you compress the insulation which prevents it from doing its job.  Therm-a-Rest has eliminated the problem by completely removing it from the picture.  This bag doesn't have a back panel, and instead it wraps around you and your sleeping pad to provide a fully enclosed sleep system.  Don't worry about any draft either because this bag has a specially modified hood, foot box and a wrap-around design that will keep the cold air out.  This bag is a great choice for gram counters.  By eliminating the less useful insulation on the bottom, as well as removing a zipper this bag comes in at just 1 lb. 6 oz.


  • Technical Performance: Durable 20D nylon shell, and 700-fill down combine with a full hood, modified foot box and wrap-around coverage to provide reliable warmth with minimal draft.
  • Exceptional Versatility: Can be strapped to any mattress, used on top in warmer weather or slip a tapered ProLite or ProLite Plus mattresses inside for maximum cold-weather performance.
  • Unparalleled Comfort: No more sleeping like a mummy, trying to find out which way is up, or searching for your zipper weve delivered room where you want it without excessive gaping for maximum efficiency.
