I'm currently in the market for some insulating tights to run in when it's cold outside (<45 degrees) and I know Underarmor has some "coldgear" tights for that purpose, but those run $50. I've been looking online at the sales at Nashbar/Performance and there are lots of cycling tights to be had for $25. Are these essentially the same thing, and will they provide good insulation for cold weather running?
Another question, how do I make sure I don't have a padded ass? What does it mean if it says it has chamois?
