I just bought 8 yards of Foliage Green 70D 1.9 oz urethane coated Ripstop from DIYTactical. It was only $4.00/yard, which I thought was a good price.

This is a lightweight Foliage Green, 70 Denier, 1.9 oz Ripstop Nylon fabric with a waterproof, urethane coating. The fabric is 60 inches wide and Sold by the yard.

Great for use in making lightweight tents, rain flys, field tarps, Ponchos etc.

1.9 oz is the weight per square yard (not linear yard) of the fabric before coating

This fabric was bought as seconds from the manufacturer but we have been unable to determine the reason why they were sold as seconds.
I know it'll be relatively heavy. If I make smaller things out of it mixed with uncoated or DWR ripstop nylon, maybe I can mitigate some of the weight.

Anyway, I think I'll have some fun with it, and see what I can make. I've needed a rain hat... Should be fun.
