Since i like poncho tarps (have a couple) i was looking at the poncho liners you can buy. Does anyone have any packed specs on them i.e. weight and packed size similar to this one http://www.thebushcraftstore.co.uk/...iner---makes-a-great-hammock-liner-9545-p.asp. Need to see if its not going to be a monster item like my wool blanket tends to be...
