The ASICS Graphic Short Sleeved Running T-Shirt features Quick Dry fabric, which uses lightweight yarns & specialised knitting techniques to create a fabric that draws moisture away from the body & dries quickly for greater comfort. This is enhanced by the inclusion of mesh panels in the garment, to help promote further ventilation for extra breathability. Additional features include UV Protection for staying safe from harmful rays & reflective components to help raise your visibility in low light conditions.
