Is it a light baselayer? Is it a Merino sunshirt? Is it the most comfortable and versatile fishing shirt you’ve ever worn? Yes, yes, and yes. Our Thermo 150 Hoody gives you the natural comfort and moisture wicking properties of Merino with the light weight, easy stretch, 50+ UPF, and full scuba hood of our Sol Hoodies. Built to be your go-to fishing shirt no matter what the weather or season, the Thermo 150 works as a light insulating baselayer when worn under other layers and a jacket, or an incredibly comfortable sunshirt when alone. We use only the highest grade Ultrafine Merino fibers, which measure just 17.5 microns, spun with just the right amount of nylon to create this uniquely functional shirt. You get all the benefits of Merino - buttery soft feel, great temperature regulation, lasting odor resistance - in a hoody that you can comfortably wear most of your season.
