The FXR Excursion Lite Boots deliver lightweight warmth and dependable waterproof protection for extreme winter conditions. Built from 100% waterproof high-quality EVA material, the outer construction uses integrated air bubbles to provide a high insulation value without unnecessary weight. The boots are cold and flex rated to -50°C for reliable performance in severe temperatures, while a triple-layer removable liner with a foil outer helps retain warmth and can be removed for drying or cleaning. A heavy-duty polyester gaiter with shock cord helps secure the upper opening and reduce snow entry, making the Excursion Lite Boots a practical choice for cold-weather outdoor use.
