When a full day of adventure has earned you a good night’s rest, you deserve a sleeping bag that fits like a dream. Our Mummy Sleeping Bag is warm, comfortable, and versatile. It keeps you cozy and tucked away after a long day of hiking, climbing, biking, canoeing or any other outdoor pursuit.

The Mummy features a hood and a full length 2-way side zipper with an integrated draft tube and zipper guard to keep it breeze-free. The zipper wraps all the around the footbox allowing you to open the bag flat like a blanket or to simply unzip the bottom to kick your feet out if you get too hot under all of that premium down.

 

  • Constructed with Responsible Down Standard certified 900 fill power Muscovy Duck down.
  • Goose and duck down are naturally water repellent, but as with any down (treated or not) it will wet out if exposed to moisture for more than a few minutes. Our Muscovy down is ultrasonic-washed. It is odor free and contains no added chemicals or treatments.
  • Each compartment is overstuffed with 30% more 900 Fill Power premium down than is necessary for maximum loft to account for any future down compression.
  • Vertical baffles on the upper body keep down from migrating to the sides. Tightly spaced compartments help keep the down evenly distributed so there are no cold spots. There are no "sewn through" seams.  
  • Our rectangular foot box is roomy, and fits the shape of your feet comfortably when lying on your side, on your stomach, or on your back with your feet angled out in a relaxed position. 
  • Black fabric on the inside for quick drying.
  • Both the .51 oz/sqyd Ventum Ripstop Nylon liner and the shell are treated with a PFAS free C0 durable water repellent to resist rain spray and body moisture. The materials do not contain any harmful chemicals such as flame retardants.
  • Integrated hood with cinch cord provides full protection from the elements for cold nights on trail.
  • Full length two way side zipper extends around the bottom of the bag allowing you to fully open the bag like a blanket.
  • You can open the bottom end and vent your feet, or flip the bag around and wear it as a cape in camp on cold mornings.
  • A draft tube stops cold air from passing through the zipper. 
  • A zipper guard is in place to prevent the zipper from snagging on the draft tube or sleeping bag material.
  • A snap at the top of the zipper keeps the zipper securely closed.   
  • Our mummy bag maintains its full width at the neck/shoulders. You can hang your arms out to vent, or reach out without unzipping or feeling trapped in a straight jacket like many other ultralight mummy bags.
  • An Elastic cord can be cinched tight around your neck to keep out drafts, or pull the bag up around your ears.
  • Shock cord can be cinched independently at the neck and hood to keep out drafts and snug the hood down around your face.
  • Roll Top Dry Bag is included, and adds ~.9 ounces (25.5 grams) to the listed weight. The dry bags are a comfortable fit and can be compressed smaller by squishing the contents and rolling the top down more.
  • All Zpacks gear has a two year limited warranty against defects in materials or workmanship. Please see our return / warranty policy.
  • Made in the USA.
