So I packed into Washington Park north of Payson Az last weekend and it got down to 22°. I was using my 0° incubator with a 0° down mummy bag with my winter incubator top quilt and hot water bottle, problem CBS...? EVERYTHING except my but and hips stayed warm and mostly to warm and cant figure out what went wrong. So my question is should I be trying a pad from mid back to mid thigh? The uq ends were synched off tight to prevent air flow and I even added a bungee in the middle to keep from getting an air gap mid quilt. And my tarp was hung low with the ends closed off and snow piled on the edges to keep wind from blowing. I was debating cutting up Reflectixs( or how ever that is spelled) or using a double reflective layer foam core car window thingy I saw at Wally world. Any thoughts or sugjestions would be nice. Oh and per hammock forums rule #1 and I paraphrase ( If there are no pictures it never happened. ) here they are.
