By popular demand, we've brought back our Reef performance shirt in short-sleeve. These shirts are made from our own HydraTech fabric, offering UPF50 sun protection combined with great wicking and antimicrobial capabilities. The fabric is smooth, light-weight and comfortable. These breathable shirts will do a better job of keeping you cooler on hot days and warmer on cool days. They'll also keep you drier and odor-free while you're out on the water. Classic SailFast!
