We needed a fabric that defined ‘ultimate’ for comfort and performance. So, we found it in an ultra-lightweight, matte, stretch polyester fabric. This ultralight 100% polyester fabric with a smooth, dense face that maintains shape and resists snagging. Developed for active movement, these hybrid swim shorts offer extreme breathability, stretch, water and stain-resistance, complemented with a light airy feel. You won't want to take them off.
