What can I say but: RANCH WORK IN 110 DEGREE SACRAMENTO HEAT!  I need to protect my legs from flies and star thistle while working on the ranch in the heat.  These pants are PERFECT.  They are very lightweight and not clingy.  Plenty of stretch for moving around. Plus - HAY DOES NOT STICK TO THEM!  A friend recommended them so I bought one pair as they seemed a little pricey to me.  LOVED them so much I bought a second pair so now I can wear them both on and off the ranch (better than going to the grocery store in breeches!) .  I'm 5'4 and 138 pounds . I usually wear a 6R but ordered the 4R and they fit perfectly. Not sure how long they will last but I will follow the advice of others and wash in cold and hang to dry.
