Product Details
Stay warm and focused in cold-weather conditions with the Grundens Grundies Thermal Bottom, a fishing base layer designed to retain body heat while remaining breathable. Made from soft, non-pilling thermal fabric, these bottoms provide insulation without adding bulk, making them ideal for layering under your fishing or outdoor gear. The moisture-wicking technology manages perspiration, while HeiQ anti-odor treatment keeps you fresh during extended wear. UPF 50 sun protection guards against harmful UV rays, and the elastic waistband ensures a snug, comfortable fit. Flatlock seams and a gusseted crotch enhance mobility and prevent chafing, ensuring all-day comfort in any outdoor activity.
