Product Details Description This Hook & Tackle ® Fish Flags performance fishing long sleeve shirt features tag flags on the back of the shirt. and a Hook & Tackle ® logo on the chest and sleeve. Most sun protection fishing t-shirts in the marketplace are made of 100% synthetic fabric. They are hot, clammy, odor-prone, do not breathe and generally are very uncomfortable. Cotton fishing t-shirts are breathable and comfortable but do not provide effective sun protection. We invented a solution called Solar System®, a breakthrough technology that gives you the effective sun protection of a synthetic fishing shirt but with the comfort and breath-ability of a cotton fishing t-shirt. We further upped the ante by adding moisture-wicking and odor-resistant technology allowing you to stay cool, fresh and protected from the sun’s harmful UV rays.
