I got some Coolmax tights at Wal Mart a few months ago.  They were called "yoga pants" and cost $10 each!  They're light weight and nice and stretchy.  They were flared and very long, but easy to take in on the sewing machine.  I also got a couple sleeveless coolmax shirts, too.  I'm always keeping my eyes open for cheap lycra tights, but I was really surprised to find Coolmax at Walmart!
