The KÜHL KILEY™ LS SHIRT features an Organic Cotton/Tencel blend fabric to combine the comfort and breathability of cotton with the strength, stretch and softness of Tencel®. UPF 50 provides protection from the sun. Knit panels on the sides allow greater freedom of movement. High-tech mesh panels are strategically placed to provide cool comfort. Colorful fabric provides a striking contrast in the travel-ready KILEY LS SHIRT.
