Since antron fleece is hard to come by in your average, run-of-the-mill fabric shop, I would recommend giving polar fleece a try; it's not nearly as fuzzy as antron, but it is significantly fuzzier than ordinary polyester fleece, and it does a pretty good job at hiding seams.
I managed to get some in the color I wanted when I began work on Steve D'Monster's new gf Bethany, and I've been very pleased with the results.
