20F Classic Sleeping Bag DISC
- 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 C0 durable water repellent to resist rain spray and body moisture.
- 3/4 Length Zipper extends to your calves. The zipper is positioned on the bottom of the bag allowing for multiple sleep set ups.
- The bag can easily be opened up for venting in "quilt mode". Most of the time you probably won't even use the zipper.
- Since the zipper is underneath you no draft tube is necessary- that means less weight and much less chance of a frustrating zipper snag. Getting in and out is as easy as turning the zipper to the side, or just slide in or out the top of the bag.
- A flat clip at the top of the zipper keeps the zipper securely closed. Or use the clip alone with the zipper opened for venting.
- An Elastic cord can be cinched tight around your neck to keep out drafts, or pull the bag up around your ears. This bag does not have a hood- wear a warm hat, or a Goose Down Hood, or size up in length if you want to pull it up around your head.
- 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.
Tired of blowing up your sleeping pad manually? Check out the Flextail Zero Pump.

A little thicker than the Nemo. It’s lightweight and does the job quite well.
– Carl S., ★★★★☆

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.
– Corey S., ★★★★★
Snuggling up next to your partner makes a cold night on the trail better, until your sleeping pads begin to slide apart. Use two or more of these sleeping pad straps to keep a pair of sleeping pads lashed together side by side.

Slept great this past weekend using it for the first time. I really like being able to control the firmness of the pillow by using the desired amount of extra clothing I’m carrying. And it’s a great waterproof stuff sack!
