Listen...these aren't just for ladies. As a male endurance athlete with tree-trunk sized legs, my thighs rub together in a way that causes chaffe. Horrible, horrible chaffe. When I'm out for a long run or hike, at the first sign of irritation I don these fancy thigh bands and experience immediate relief. I can put them on without even taking off my shoes or running shorts. Just slide them on and friction is banished! The silicone rings on the top and bottom keep them in place relatively well, all things considered. They're very breathable and I forget I'm even wearing them.

My running partners tease me for wearing "ladies undergarments" but I can bench press more than any of them, so it all evens out.
