Seems, with the extremely dry air out here in the southwest I need a groundcloth to keep my tent floor (Contrail) from getting very dusty/dirty with the "talcum powder" type dust we have compared to back east.

So, I'm back to using clear contractor 1.5 mil thick plastic sheeting cut 2" smaller than my floor dimensions.

Once I made a plain ripstop groundcloth for a hooped REI SoloLite. I sewed small hems W/ loops of elastic cord at each corner to loop over the tent stake pullouts. Worked well back east.

Should I be looking at uncoated ripstop? Silnylon?
(Tyvek is not a contender. It's a debris magnet.)
