I'm a ground dweler thinking about a hammock setup. I've got a decent light weight 3 season setup now (6'6" 20 deg down bag @ 2lbs and a 26 oz one person tent with an 8 oz pad). My question is cant I get down to this weight with a hammock setup and be comfortble down into the low 30's? what kind of money should I be ready to invest? Thanks in advance.
