Warm in Wyoming
I spent 4 nights in the Wind River Range. This is my first quilt, and I was comfortably warm with temperatures in the 30’s each night. It compressed very well, so it didn’t take up much room in my pack.

I'm very impressed with the quality of this quilt. It's well made and lightweight. I can't wait to field test it. My only concern is if there may be cold spots if the down shifts in the baffles, but when I fluffed it, I wasn't seeing light through it, so we shall see.

Love my sleeping Quilt
Cozy, warm and compact. Slept with it when temps were in the high 40s so not super cold. As a side sleeper I was so much more comfortable than sleeping in a bag. Highly recommend!
