Coming kinda late to this party, but here’s something that I don’t know if it’s been tried or not. I’m not even sure exactly how to do it, or if it would even work, but since you fine folks at HG have better resources to try things here it is...a half-bridge hammock. Head end would be gathered end style, but the foot end would have a spreader bar. My reasoning is it would eliminate calf ridge (and one spreader bar over a conventional bridge so it would be lighter).

While I’m thinking about it, have you ever tried to design a top quilt to eliminate calf ridge? I have a Burrow with a sewn foot book and wondered if maybe having some kind of pocket under my knees I could slip a foam pad or some clothes in there to cushion that calf ridge would work. I’ve tried external pads and pillows to mitigate calf ridge, but the internal pocket would keep the cushioning in place. A calf ridge eliminating top quilt. Would be a marketing first.
