I was thinking that I had 1.1 light weight ripstop nylon from Walmart. Olive drab, uncoated best I can tell. Somewhat see thru. No water tests as of yet.
I cut a fold test piece 1'x4' and had a scrap 1'x1'.
I weighed them both using a triple beam calibrated to the gram. Each averaged out at 6.5 grams per sq ft.
So 6.5 x 9 = 58.5 grams per sq yd = 2.06 oz per sq yd
Thinking the material slightly dusty maybe and with oil from my hands would it be safe to say I have 1.9 material?
