I mainly used this when riding motorcycles that generate a lot of heat. Also, when wearing it, I always used a cooling inner layer between the product and my skin. I've used it about 5 times. Regarding the fit, the XL size of this product was just right for me, while my motorcycle pants are size L. Many product reviews have similar comments, so it seems that those who usually wear L would find this to be a perfect fit. Retail price: 7,968 yen
