After lots of research and finding ways to cut weight, I purchased the 15 degree quilt. Wasn't sure if it was right for me but pull the trigger for my backpack hunting trips. Went out for 3 nights to give it a try on opening day, used it and like it a lot. I don't strap it to my pad but having the ability is a huge plus. Foot box is comfortable and still allows a lot space. Packs down super small and tight and of course the weight is hard to beat. Kept me plenty warm. There is a smell to it when you get it that is different(can't seem to tell what it is) but wouldn't call it a bad smell. I left it hung up to air out and come to full loft for 2 weeks and the smell basically went away.
