The quilt started early this year. I took it with me this weekend - and temps got lower than expected. Most reliable local weather called for 37 Saturday night. It must have been lower than that because I woke up to find the dogs water bowl forzen. I guess it dipped below freezing last night. The quilt did good. I never even realized it was that cold.
So I am going to give the quilt a 32* rating. Better than I had expected. I might be taking the quilt on my Benton Mckaye Trail trip. I would rather have a synthetic, but am not sure I would have time to make and test one before hand.
Using MYOG gear is very satisfying.
