Extra warmth for minimal weight
I used this during a recent 3 day competition where we had to carry all of our gear and camp outside. Winter storm was predicted so I got this to bolster my sleeping bag. It got down into the teens and we had 5”+ of snow one night. This definitely helped keep me warm, especially sleeping on an ultralight foam pad.Packs down small and doesn’t weigh too much for the warmth it provides.Probably way overpriced for what it is (someone with basic sewing skills could probably make this for half the price), but if you need some extra insulation that doesn’t get too much in the way of sleeping, this is a good purchase.

Would highly recommend for backpacking
Very satisfied with this purchase. Worth the price because it serves dual purposes so displaces other heavy gear in a backpack - camp blanket around the fire, sleep liner on chilly nights for extra warmth, and summer sleep sack for overnights in hot weather when you don't need a heavy bag.

Sleeping bag liner.
This bag liner is nice and warm. Drawstring bottom is great for sitting around the fire and keeping your legs warm. The snaps and hood helps keeps wrapped around you while you roll around at night. Was out for a cold evening and usually sleep in my puffy. Ended up taking it off in the middle of the night cause the liner was keeping me extra warm.

Kept me too warm. almost
I took this mummy system on a trip to Maine on an overnight in temperatures in the single digits and teens. I was so warm, I had to unzip my sleeping system to let out some heat in the night. I am very happy with the quality of this sleeping system.
