Warm Active Insulation Pants Using Octa These are the Slick Pants, active insulation pants, based on the same concept as the SLICK HOODY. They use breathable "Primeflex" for the shell material and "Stretch Octa," a breathable and insulating inner material, is mapped throughout to enhance heat retention. Both fabrics have high stretch, and the pants are very soft to wear. The three-dimensional cut and tapered shape below the knees eliminate excess fabric while not hindering the movement of the hip and knee joints. Fabric: The outer fabric uses 20-denier "Primeflex" with DWR (durable water repellent) treatment. It excels in breathability and stretch. The lining uses Teijin's Octa. It's a lightweight, warm, and highly breathable functional material. Waist Specifications: The gathered elastic on the sides and back enhances the fit, and the front has a cord for fine adjustments. Pockets: A zippered pocket on the right hip. Waist pockets on both sides. They have a slight angle, making it easy to put your hands in and out. Packable: Packable design that allows the pants to be stored in the zippered pocket on the right hip for compact carrying. Ventilation: Zippered ventilation on both sides of the thighs. Effectively ventilates. Used only a few times for everyday wear, with no noticeable stains, tears, or other damage. There is little wear and tear, and I think the condition is good. Octa lining throughout makes them very warm. Please refrain from purchasing if you are sensitive to used clothing.
