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.
