This is a wearable sleeping bag--use it to keep yourself warm on your patio or by the fire, it's basically a blanket you can walk around in. I no longer live in New England and I no longer have a backyard so don't have a use for this. I was inspired to purchase this by wirecutter -- see here: https://www.nytimes.com/wirecutter/reviews/best-wearable-sleeping-bags/ "Cut close to the body, this order-by-height bag allows for a slightly customized fit to help keep you warmer. The Napsack’s curved armholes and drawstring bottom make movement easy, and this feels like a solid-quality bag for the price."
