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.
Kept me warm in the 20s on the Sheltowee Trace Trail in KY. The zipper is hard to use but it seems the more use it gets it works a little better. For the price range it can’t be beat.
My son bought this per the recommendation of his hiking/backpacking buddy. They are both 18 and time alone in nature has been their mental health break in 2020. This bag keeps him warm, is comfy and well-constructed. Not to mention the customer service is exceptional and personal. Our son asked for a tent and a sleeping pad from this company for Christmas and we got him both. We expect those to be five stars as well.
