For your HH Explorer Deluxe, it's PU coated (as stock). The Expedition Asym, Explorer Deluxe, Scout and both Desert models have the 1.9 oz PU coated tarps; all others come with silnylon versions.
My knife is so sharp it cut the sixth finger off my right hand! On the plus side, Inigo Montoya no longer hunts me.
This seems like a decent camo tarp despite the weight for the $$$. I can't seem to find a cheaper one that is cat cut along the ridgeline...
If you really want camo then go for it. For 1/2 the weight you can get the same thing in silnylon. But they do not make camo in silnylon.
