After reading Andrew's awesome write up on that quilt he made, I was thinking about making one as well for general 3 season use. I would use 5oz apex for the insulation, and some 1.1 nylon for the shell.
My current bag is a SD Nitro 30, which is an awesome bag, but its almost too warm. I've slept in it with just a silk base layer down to 28, and was toasty (I am a very warm sleeper though). Like 95% of my backpacking never even gets below 35. The bag weighs around 29oz though for my long version. So what I was thinking that if I could make a quilt that weighed about 20oz that would be a nice weight savings.
I always carry a patagonia nanopuff that I never even use at night, so I mean, I could always utilize that as well. Do you guys think the 5oz quilt paired with a nanopuff could get me down to 30?
