When I used to fly aircraft, I didn't care much in what I wore, as you were either going to land, or crash, there was little in between. Clothes wouldn't have made a difference. You didn't have a parachute or an ejection seat. When I ride, I always suit up. If I have to dress at an event, I carry that clothing in an appropriate case. I never ride, don't care if I'm going for a hot dog, or long ride, without being suited up. If I get taken out, it won't because I wasn't dressed right. I've seen people with skin hanging down. I'm sorry, but you offer to younger riders a really bad example.
I wear Fieldsheer jackets in the Summer and they keep you cool. Leather gloves with Carbon Fiber knuckles, extra heavy duty palms. I wear heavy duty jeans, Harley Davidson riding boots, (they make a damned good riding boot) and a full face helmet.
Dress up appropriately when you get on your bike. Forget about judgement, that doesn't come into play. Physics is involved here, not feelings and judgement. Someone else's judgement will kill you. Think of the physics involved, and what will happen if you're involved. I never drunk and rode. in any decade. Yes, I can party with the best of them, but then came the sofa, and a new day, not getting into vehicles of any kind, especially with the people I just partied with. Pure physics, your lose if not dressed right, no matter how you have judged the situation. I've seen guys in suits riding bikes, I won't post what I think about that. Maybe they have some magic "John Wick" fabric that will protect them. It doesn't exist. When the guy not paying attention runs you of of the road, or something you just could not predict, that "suit" will do nothing for you. This is too serious to be glib about. We older riders need to set the example. I've been riding since I was 17, I will be 65 soon. People will ride like they wish ultimately, but I don't ride with people who aren't geared up. I se people on bicycles going 40 mph down a hill with leotards on, and I have seen the aftermath when their skinny tires blow because they hit something from the side of the road, punctured their front tire, and they are a mess, broken jaws, lost skin, broken arms, etc.. They didn't have a 400 to 500 lb. bike to kick away from them. Just my 2 cents worth.
