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
