The Grundens Grundies Thermal Pants give anglers a warm, low-bulk fleece layer for cold boat decks, ice shelters, steelhead wading, and early-season salmon, walleye, bass, or trout trips. These black heavyweight stretch fleece pants use thermo-regulating properties to help manage warmth during changing activity levels, while tapered legs fit cleanly under deck boots and inside waders without bunching. Zippered handwarmer pockets add secure storage for small essentials, and HeiQ odor control helps keep the layer fresher through long days and repeated wear.
