20F Mummy Sleeping Bag DISC
*Mummy Sleeping Bags can now be found here*
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 goose down.
- Constructed with responsibly sourced and 'Responsible Down Standard' certified DownTek PCF-FREE water-resistant 900 fill power goose down which stays dry 90% longer than untreated down.
- Each compartment is overstuffed with 30% more 900 Fill Power Premium Goose 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 liner and the shell are treated with PFC Free C0 durable water repellent to resist rain spray and body moisture.
- 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.
- A 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.
- Our sleeping bag shell materials do not contain any harmful chemicals such as flame retardants. Our shell is treated with C0 Durable Water Repellent, which is free of PFOA and PFOs

Neoair Uberlight Sleeping Pad
What I love most about this sleeping pad is its light weight, and that it packs up very small. I had to send the first one back because of a leaky valve, but received a replacement very quickly. I love the new valve design - it’s very easy to use, and very efficient.
– Constance D., ★★★★☆
As the absolute lightest insulated air sleeping pad available, the NeoAir UberLite is the top choice for thru hikers and ounce counters, setting a new standard for ultralight comfort. The unrivaled Triangular Core Matrix offers the best warmth-to-weight ratio of any air sleeping pad construction, creating a 2.3 R-value. The construction gives the 2.5 inch (6.4 cm) thick pad superior stability for maximum camp comfort.
The ultralight sleeping pad features the high-performance WingLock valve, allowing the pad to inflate three times faster thanks to a larger opening and one-way inflation. Like all Therm-a-Rest pads, the NeoAir UberLite is made in the USA to ensure quality and minimize environmental impact. The pad includes a breath-saving pump sack, compact stuff sack and field repair kit.

A little thicker than the Nemo. It’s lightweight and does the job quite well.

Sleeping Pad Strap
NOTE: This item is a single strap. Make sure to order at least two straps! Three straps are nice for full length pads.
Used them with my significant other in the [Smokeys] last month and it is so nice to keep the pads from sliding apart and staying cozy. Simple and light design. Would recommend for couples who want to stay close at night.
