I have a Macna dry cooling vest for sale. You fill the vest with up to 500ml of water and then squish it around in the vest to spread it out. Once you start riding your body heat and air passing over the vest cools you. This should last about three days riding. You don’t feel wet in the vest but you do need to be wearing some sort of airflow jacket. It’s as new with the original box. I’ve only worn it twice on tours in Europe, and it does cool you down as long as you are riding at a reasonable pace (not in town situations) The issue I had is that I wasn’t getting enough airflow behind my Multistrada’s touring screen. I suspect it would be much better with a short screen on something like a Pikes Peak or sports bike.
