A sleeveless running shirt with a bold print of the crossbone motif that Eldoresso is good at, and switched to different high-performance materials on the front and back. Eldresso's running wear, which is created with free ideas that are not bound by existing molds, is characterized by the creation of a fusion of functionality and fashion that reflects the designer's experience in apparel over many years. At ELDORESSO, the designer himself repeatedly tests various functional materials in practice and selects the fabrics to be used in the products. For the front of this product, we have selected a functional material with a silky touch that has a UV cut effect. The back body has been switched to a water-absorbing and quick-drying mesh fabric, achieving even higher quick-drying performance. The pocket that is convenient for storing small items created by switching the fabric on the right back side, which has been popular since before, is still alive.
