I have a 45 degree bag and I'm in a hammock. I'm purchasing a sleeping pad for insulation and looking at bag liners, I don't want to buy a new sleeping bag. What materials will be the warmest? I've been looking at silk and fleece liners, although I assume the silk will take up less space. I found this: Gizzly Soft-As-Silk Microfiber
Bag/Bed Liner
Any idea if this will be enough?
thanks!
