So I have this DIY Survival Blanket a family friend made. Shown in the photos below. I was curious if maybe I could use this for a under quilt somehow? It's a little dirty with stains on it cause I can't wash it. There's some sort of insulation material on the inside, as well as a emergency blanket (why I can't wash it), and some other things. When ground camping in the winter, I would use this below me. I could walk barefoot with snow still below. It kept me plenty warm. My first winter camp I had this and the MSS and I survived the night. Combined with a spare summer pad someone brought, I slept good enough when the MSS stayed closed, which wasn't often. The second trip I went on I had a Big Agnes Q Core Sleeping Pad (I learned my lesson fast the first trip) and I used this as a group floor then. Don't know why but I kept falling from the sleeping pad but the white survival blanket did really well combined with a SubZero Surplus Bag I got to replace the MSS. I was pretty toasty in that and would use it again, if it wasn't the same size as my large laundry basket when closed. The original purpose was to put on the windows of my brother's current place during the winter (there's no insulation in that house) and when he did do that, he stayed plenty warm. So it's seen uses and done well. The question is can I do something at all to turn it into a under quilt to keep me warm during the winter while in the hammock? It'd be paired with a ENO Double Nest. Inside the hammock I'd be using a wool blanket above me and a sleeping bag inside that. Below are the photos.
