The Grundens Grundies Thermal 1/2 Zip gives anglers a warm, flexible fleece layer for cold boat rides, ice fishing setups, steelhead drifts, and early-season walleye or bass trips. This black heavyweight stretch fleece uses thermo-regulating properties to help manage warmth during changing activity levels, while the deep center-front zipper adds fast ventilation after hauling gear, drilling holes, or working around the deck. A chest storage pocket keeps small accessories close, and HeiQ odor control helps keep the layer fresher through long fishing days and multi-day trips.
