Just a hair under a pound. I reinfoced corners and guyline areas with scraps of cordura. picked up a ounce or two there. I figure it will last longer? I can use Hammock under it yes,but primarily for smokies trip with my son to cook under. Hopefully will give us some extra protection if it gets nasty. I dont want to cook under hammock tarp,as areas we are staying are under a heavy bear allert. I dont plan to be a snack!
