Thermodown 0 Sleeping Bag
Cold weather is no match for our 4-season Thermodown 0 down backpacking sleeping bag! Each bag lofts to almost 6 inches to keep you toasty warm during those freezing nights in the backcountry.
Stay warm and comfortable, no matter the season, in our outstanding Thermodown 0 down sleeping bag. With excellent materials and performance, your search for a great four-season sleeping bag ends here!
Cold weather is no match for the 32 oz. of 700-fill power down insulation stuffed into every corner of this bag. You will stay toasty warm down to 0F (-17C). However, the added warmth does not compromise on size and weight. The bag packs down to just 11 x 8 inches and comes in at only 3 lb.
We've done our best to make this a great bag.

How do I care for my new down sleeping bag?
- When you first receive the bag, run it in the dryer at the low-temperature or air fluff setting for about 10 minutes to loosen up the down that has been compressed during the shipping process.
- When heading out on the trail, use the included compression sack to protect the bag and also reduce the amount of space it takes up in your pack. Use care when stuffing the bag into the compression sack.
- Between trips, always store your bag using the included mesh storage sack or the hanging loops.
- Always wash your bag by hand or a front-load tumble washer. Never use a top load washer. Never use bleach.

How do you determine the temperature rating?
We've put together an in-depth article on how we determine our temperature ratings. The guide also provides lots of helpful advice regarding making an informed decision.
How can I increase the temperature rating of my sleeping bag?
If you'd like to use our down bag at temperatures of 0 degrees and below, you may consider adding a sleeping bag liner to add about 10 degrees to the warmth rating. The Sea to Summit Thermolite Sleeping Bag Liner is a great option.
