Merino has stood the test of time when it comes to high-performance insulation. It traps heat, wicks moisture, naturally resists odor, feels great against your skin, and functions well even when wet. The 260 Line expands our popular Thermo Collection, giving anglers a midweight option between the 150 and the 350. Built with 95% 18.5-micron Merino, the 260 Top makes a perfect standalone shirt for cool fishing days but also shines as a heavy baselayer. Wear it under a midlayer (like the 350 Hoody) and an insulated shell (like the RS Outpost) and you can fish comfortably through arctic conditions. The quarter zip neckline with an extended collar lets you dial in your heat retention, and a double jersey knit interior and exterior combines comfort with durability.
