I purchased a second Radiator Mesh Jersey because I love and wear my first one so much. It is perfect for hot weather racing. I have worn these now for the Worlds 24-hour Time Trial race and, just recently, for the Race Across Oregon. My first purchase is still good as new after many, many wears. I purchased a second in case I need to change a kit during one of these long races or if the other is in the wash. The fit is perfect, which is a rarity when purchasing an XS jersey. It fits in the bust and at the waist. The pockets are perfectly positioned. The material is lightweight and very breathable. I now have two of the red-orange color, which is highly visible and just a great color. I also have a green, but the red-orange is my all-time favorite.
