I don't remember when I bought it, but I purchased it new and stored it without ever using it. The front is made of windproof material, and the rest is as follows: This is a description of a product using the patented material "MAXIFRESH® PLUS." It's a high-performance material with deodorizing, heat-retaining, and antibacterial functions, providing a comfortable fit. It powerfully cuts "sweat odor" and "aging odor" components. It has a comfortable heat-retaining function due to the far-infrared effect of the photo-electron fiber. The deodorizing and antibacterial functions do not deteriorate even after repeated washing and last semi-permanently. It features a flat-seam construction on the skin side for a stress-free fit and a silhouette that fits, considering the riding position. Thank you.
