AFTCO and Guy Harvey have teamed up again to market a line of young men's fishing T-shirts. The YMTH collection features Harvey's classic style but employs slightly different technique, placement, color and printing treatments, such as soft hand inks, gel screens and foil, to distinguish it from his men's line. The shirts, made from 412-ounce combed ring-spun cotton, also offer a slim, athletic fit for the younger set. Designs include redfish, billfish and tuna. YMTH Ts come in sizes S through 2XL and cost $22.99. Call 949-660-8757, or visit www.aftco.com.
