Designed for fishing in hot and humid conditions, our Tropic Comfort 1/4-Zip lets the steam out with a deep-zippered neck for instant relief and temperature regulation. The ultralight 94% polyester/6% spandex stretch fabric provides 50+ UPF sun protection, wicks away perspiration and keeps things fresh with Polygiene permanent odor control. It also floats over the skin with a soft, cotton-like feel so you can stay cool and focus on the task at hand. Long sleeves with thumb holes keep the backs of your hands covered, while the gusseted underarms allow freedom of movement for casting or reaching for the big high-five when that permit finally decides to eat. Fair Trade Certified sewn.
