I want to make some running skirts, which are similar to tennis skirts. They are typically made of out nylon/spandex wicking fabric (Coolmax is one well known brand.) I have found quite a few sources, but I was wondering if anyone here can suggest a reputable source, either online or in real life. I'm not sure exactly what I need if I can't touch it, so somewhere with a live person would be great.

Thanks in advance!
