Has anyone used this groundsheet? The 28x83 is supposedly 3oz and claims to be waterproof (20D nylon treated with some kind of silicon, hmm). For $17 it seems like a good deal if it works as advertised.
See if you can find ripstop silnylon in a good camo print like multicam, Cadpat, , MARPAT, flecktarn. Good for stealth camping !

20D Single side coated silicon 360T Nylon Fabric
About 200cm square for $27 is a good price. I'm thinking of getting one for a tarp and just sew in more tarp pullouts. Looks like a neutral tone earthy gray colour.
