Most of the time, I wear jeans, boots, hi-vis jacket with armor, leather gloves, and a full-face helmet. If I am staying on-post, I will slide out with a long-sleeve white shirt, and the other pro-gear.
My son doesn't have any real gear yet. He has a 3/4 helmet and wears eye-pro, his dirtbike gloves, elbow and knee pads that he'll wear along with a long sleeve shirt, jeans, over the ankle footwear, and a hi-vis vest. He is 7. I want to get him a jacket, full face helment, and leather gloves, but that will come in time. I don't take him off-post here in El Paso, and the speeds on post are 25-35 where I do take him.
Soon he'll have all the gear since we are getting him a dirt bike and gear this Christmas...hopefully this is a success and not a flop.
