As a ground dweller, (the name hammock users give me), I have a pretty lightweight setup: 24oz shelter, 20oz pad and ground cloth, 24oz quilt. (24+20+24)/16 = 4.25lbs.
It is hard for me to know if this is all correct, but it looks like I would have the following for a hammock setup: WBBB D1.7 = 40oz, 3-season Yeti UQ = 12.5oz, small pad = 10oz, 3-season TQ = 24oz, Tarp = 13.5oz. (40+12.5+10+24+13.5)/16 = 6.25lbs
I would carry 2 extra lbs - not a big deal, and shell out a minor mountain of money.
What do I really get by going to a hammock?
