All I can think of to describe what I'm designing is the Cadillac of hammocks.
Long story short, I'm looking to to design a hammock for cool weather, but also for many nights stay in the same location.
I camp a lot during the spring and fall. I also have a few 5+ day trips which would see me leaving the hammock setup for some time in the same spot.
Weight for this hammock is not a huge factor as I'll be travelling via boat (kayak/canoe) or hopping off a train in the middle of no where.
So far I'm looking at incorporating an (thermal reflective) insulated layer into the hammock itself. This will provide warmth, but not have to worry about a pad or similar moving around on me.
I'll include two tarps, one with a thermal reflective layer (for cool weather) and one without. This should help reduce the sleeping bag or quilt weight/size.
A built in head and toe bag (box?) will be a must.
What would more experienced hangers consider incorporating into their hammock if weight wasn't an issue (within reason of course)?
