The Speed Thermal pants are lightly insulated ski pants designed for high-intensity cross-country skiing in cold conditions. These technically advanced pants feature a light-padded, windproof and water-repellent fabric at the front and calves, combined with brushed elastic jersey and fleece lining at the back for enhanced breathability and freedom of movement. The result is a highly functional garment that offers excellent weather protection, moisture transport and body-temperature management during intense workouts on cold winter days. Additional features include a bonded elastic waistband, zippers at the leg endings for easy on and off, bonded elastic at bottom leg for a snug fit around ski boots, and a zip back pocket for secure storage of small items.
