My husband has Multiple Sclerosis and stays incredibly active. He has been blessed to not experience issues with overheating, which is a common side effect of MS, until this summer. He did not want anything heavy and did not want to deal with a water-cooled vest. I got him an Ororo vest in 2021 because he has struggled with always being cold in the winter. Word spread in my family and we got them for several relatives and they were a hit. I am quite sure my 91 year old mother keeps you all in business….she owns one of everything. LOL. I was telling her what I was looking for and that I wish Ororo made something to keep you cool, and she told me “they do!!” I was thrilled to find exactly what he was looking for. This jacket is so lightweight, has zip off sleeves, and comes in his favorite color. He set up and tore down from a gig while wearing it and do not feel restricted or weighted down at all. We love it!
