I could be a spokesperson for Ororo! I researched a lot of heated vests before purchasing my first vest…the zipper has just recently gone on that first vest, I now have three vests. I wear one at work, in a barn ,and it has held up with the rigors of barn work. The other I have for other occasions and running errands. All of my family members have Ororo wear as well and now many of my riding students and family members do as well. Keeps us warm while riding horses and being in the barn. Have also used it as a “heating pad” so to speak when I have had issues with tight muscles. My vest is a game changer!
