It works for Tour players. But there is nothing that looks goofier than a 10 handicapper wearing pants on a hot July day to look like a tour pro. There is just no need!
just FYI, not everyone wears long pants to look like a tour pro. my Dad was not a scratch golfer, but always wore long pants. there was some chemical courses started using that gave him a rash if he wore shorts. started about 5 years before he died (04ish), anytime he wore shorts his ankles would have a rash by that night.
so next time you're snickering at that 'bad' 10-handicapper trying to look like a pro, don't forget he might not be the goofy one.
