I think I did. I'm thinking I added a lightweight fleece blanket to the HHSS those nights instead of throwing it into the hammock with me like I do sometimes.
Other thing to note, is that I slept in mid-weight winter baselayers (top and bottom), heavy duty wool socks I keep specifically for sleeping in, and a wool buff on my head most of the night.
I also do NOT use a sleeping bag like a top quilt...I use it like a sleeping bag, with me crawling into it and folding it over the top of me, or zipping it up. It's a little work in a hammock, but spreading/laying it out before you climb in helps considerably.
I've found that FOR ME, this is warmer than using it as a topquilt.
Again...take note of specifically WHERE you're experiencing the cold on your body...that can help you zero in where you need to improve your insulation.
