Built for the days when your fingers tingle from releasing happy trout into icy water, our Thermo 350 Hoody gives you warmth and comfort in almost any fishing conditions. The heaviest base layer we make, its 95% hand-selected New Zealand Merino wool. A full hood and extra high collar keep you fishing when things get really bitter. With a fluffy, fleeced wool interior and a durable knit face exterior, this is the shirt that shorn sheep wish they could wear. If they did, they might never grow wool again.
