Love my hammock-camping rig. I've used it for mini tours and weekend bike-camping trips many times. I'll be trying it with a bikepacking set-up in the near future. Right now the whole set-up: hammock, underquilt, overquilt, and tarp takes up about 21 liters of space, but my quilts are synthetic, so they don't pack down that small, and I'm not using any compression sacks, so I feel like it could be a fair amount smaller, but that would just free up more room for more junk, so maybe not necessary.
