Directions
Fabric Care Instructions
We recommend washing your bag in a front-loading washer. Never use an agitator-style machine as the motion can damage the stitching. Make sure to wash your sleeping bag on the gentle cycle in cool water with a down specific soap/gentle detergent. To dry your sleeping bag, set your dryer on the no heat setting and check often. If it is too hot you will run the risk of melting the fabric on your sleeping bag. The fluff or tumble setting without heat is the safest way to dry your bag. When the bag is nearly dry, add two or three clean tennis balls or a pair of clean sneakers to the dryer. This will help break up any clumps in the bag and will help to restore the loft. Make sure your bag is thoroughly dry before placing it in its storage bag.

Great sleeping bag at a great price
We used this bag last week for a three-day trip (car camping) and it was perfect for what we needed. Comfortable, packs down well and I'm sure we'll get years of good use out of it. Teamed it with a Klymit sleeping pad and it was a great set up.

Super comfortable and warm, I have used it for cooler Montana nights, and people oftentimes ask to borrow it rather than using their own sleeping bags. the size of the bag is super nice as well and can pack down for backpacking/ or easier camping organization

Awesome bag
Used on a few hiking trips, the aspen packs down decent, but is very warm. If you are taller than 5’7-5’8 I would get the large. It’s pretty tight height wise at 5’7. I really like the material, its extremely quiet instead of making noise every time you move
