Our regular sleeping bags have an awful nylon/poly type of fabric that is miserable against your skin, making it very difficult to fall asleep. We bought these fleece bags to serve as a liner for the yucko ones & boy did they work *superbly.* Total comfort. Can't state enough how big a difference they made to our camping experience.
Washed in our front loader & line dried, as per instructions - dried quickly.
We just purchased this bag on a trip to Maine, when the weather was too warm for our other bags. It felt fine for the warmer Maine September nights, but I needed something extra when the weather turned a bit colder...so, we returned and bought another one and doubled them up! It's a good buy, especially with the Bean guarrantee.
