De Soto Evolution Jersey has evolved from the designs of all the singlets, tri tops and cycling jerseys DeSoto has made in the past. The result is a great top for cycling, running, training and racing. The body and sleeves are made of Alta Coolmax® with Liquid Mesh™ Lycra® side panels and pockets. It also has our original back pocket and 16-inch front zipper of all past De Soto Jersey styles.
