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. Designed to pair with the 260 Top, the Thermo 260 Bottom makes a perfect midweight baselayer for your body’s southern hemisphere, giving you a lighter under-wader option for warm days or big hikes. Built with an 95% 18.5-micron Merino, the double jersey knit interior and exterior combines next-to-skin comfort with long term durability.
