Guide Gear Tarp is similar to the Kelty Noah 12 x 12.
It costs about $30 shipped.
It has lots of tie outs, but you have to add two to make it work in the traditional winter hammock mode.
It weighs about 32 oz (I thinK)
For some reason it disappears and yo ucannot find it online until around October each year. I think this is about half the price of the Kelty.
The Chinook 12x9.5 is also a big tarp.
It costs about $30 shipped
It weighs about 32 oz
You do not need to add tie outs (Well you do if you dont want to use grommets, but its good to go out of the box)
It also disappears until around October.
I have both and like both. They are considered heavy by many people on this forum. But when I upgraded from a "blue" tarp I thought they were miracles of technology.
Chinnok also makes one which I have not seen which is circus tent size.
I think it is 12 x 14
