I originally purchased a Campmor 9.5 x 8 coated nylon tarp for warmer weather and a car camping winter tarp - a Chinook 12' x 9.6' - bulky and relatively heavy.

So I am evaluating a discontinued Kelty Grand Mesa tent footprint as a tarp for 30 bucks.

PU coated 1.9oz nylon taffeta weighing 21oz 108x90

Campmor tarp is rated by REI as 26oz and on factory label as 30oz.

Figured difference is grommets and heavier PU coating on Campmor bring it to 3.7oz/sq yd 114x96.

Kelty footprint more like RayWay tarp weight.
