Does what it claims to do.
I am happy with the reduction in butt burn and cooling affect the seat cover provides. One note, it also makes the seat "slippery". So, items placed on it, like sunglasses, or phone, will slide off. That also affects riding position during hard braking etc. Overall though, I have recommended it to motorcycle patrol officers in my area as well as my riding friends that ride long mile days like I do. Stated simply, I would buy it again.
