Pantyhose is the answer. Years ago we had been in a stock camp, mustering every day for weeks, winter time, with bleak dry weather. One night , after a particularly hard day, a lot of galloping, a young bloke asked me if my legs were sore. I said yes they were a bit chaffed ,why. He pulled up the leg of his jeans and he had a blister , from the bottom of his calf to his knee. For people that have,t ridden horses , riding toey horses chasing toey cattle over rough country ,you have to ride fairly tight. Grip with your knees. If you happen to get sweat from your horse on your trouser legs , makes it worse ,feels like you are rubbing your legs on concrete . Well, somehow I sent a message back to my wife , asking to possibly send something up for him to put on his leg, when along with some tucker and fresh dogs, is a bag with a couple of packets of brand new pantyhose , and a note saying try these,turned up. I did keep my promise , not to tell anyone, but after 35 years , I think he would laugh about it
