I used this on my tarp for reinforcement points and to patch an existing backpack.
Lovely and easy to sew and cut. May be overkill for a 1 osy silpoly/silnylon but highly recommended.
Seam grip holds very well to this. Silicone also holds, but peels easily so needs a stich.
I made a backpack using the blue and lime green 210D. The material feels sturdy and was easy to sew
I just could not seem to find waterproof ripstop over 70 denier that didn't cost a ton and that I wouldn't have to get direct from another country. So I was thrilled to find this! The Steel Blue ended up being more teal than I expected but its still a nice color and didn't cause a problem. If I ever need more I will certainly be buying here again
I bought the 210d for a fanny pack (used it for both the outer fabric and lining) and it worked great! Super durable feeling and great color! Will definitely buy more for future projects.
I bought some of this as well as the 420D Robic. Both fabrics are very nice. They do fray a bit when cutting though, so if you have access to a hot knife, that will be better than scissors. The 210 is more flexible than the 420 by quite a bit, so if that is important, then best to go with the 210. The 420 is a much more robust fabric. I'm running some shock cord through some edge binding I made from 210, and I expect good results.
