Don't think patchwork, heavy, decorative quilt. It's really just a blanket stuffed with insulation, just like your sleeping bag. No zippers might make it a little lighter even. I don't know because I just use a mummy bag that I drape over me instead of zipping up. But if you have a system that works, use it. For me, no matter what bag I'm using, if the temp drops below 60 or so, I get cold underneath. The bag gets compressed, the insulation is compromised, and the air underneath steals my heat. That's what the pad was for originally. It's a cheap source of insulation that does not compress as much when you lay on it. I found it uncomfortable. More uncomfortable than being cold. But if you're staying warm with what you have, no problem.
