Our new performance 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. Aptly named The Grinder, these could possibly be the hardest working shirts on the water.
