Mesh gear, at the very least, FTW. I'll admit that at one time I used to drive a whole ½ mile down to the beach in tennies and shorts so I could go snorkeling. I couldn't enjoy the ride however, because I knew someone would cause me to have an accident, and I didn't want to deal with skin grafts. These days, I can't even ride in jeans without worrying about my kneecaps.
Dress for the crash, not the ride.
