I'd like to take advantage of the HG sale. I already own a Summer Phoenix, which I purchased used from a fellow HF member, and I love it. I have stayed warm into the high 40's with that and a 2QZQ UQP plus a light summer sleeping bag as a top quilt.
So as I was considering whether I should try to scrape together the funds to buy an underquilt for cooler weather, I started to wonder whether I should go all the way to a winter quilt or could I get more versatility by purchasing a 3-season quilt and perhaps stacking the summer quilt and the 3-season for those times I might want to winter camp. Has anybody out there tried to "double up" quilts? I am thinking about wrapping the 3/4 length Summer Phoenix with a full length 3-season Incubator.
