I have tried various jackets, ponchos and trash bags. I think the main concern for me is being cold. A few years ago, I was not paying attention to the forecast and wore a no sleeve jersey. I was so cold when it rained. luckily, a team member had extra arm warmers. That helped. Then a random rider handed me a plastic shopping bag and said put it under your jersey. That guy is my angel! I was warm and able to ride comfortably! Now I have a few shopping bags in my bag so I can return the favor. I wear sandals so no soggy shoes for me.
My biggest problem is I need to wear my sunglasses/glasses and can’t see very well in the rain. Anyone have a solution, other than contacts or laser surgery!?
