Leg warmers are good down to 30 degrees - doesn't get much colder here
Themoflex material is warm without feeling heavy. Lycra surface sheds road dirt fairly well. Kind of an odd cuff at bottom than looks like an unbuttoned shift sleeve cuff that you can leave down or fold up (-f2) depending on your length preference. Elastic gripper at top has tacky-rubber-like grip on inside and outside making it solid underover shorts. Great buy on sale.
