Thank you for viewing! These are Uniqlo's cold weather gloves. The inside is made of Heattech material, so they're very warm. Product Type: Gloves (Heattech Liner Function Gloves) Brand: UNIQLO (Uniqlo) Color: Navy (Dark Blue) Size: M size (Unisex) Features: The outer material is windproof and water-repellent, making it difficult for wind to pass through. The lining uses the moisture-absorbing and heat-generating material "Heattech". The thumb and index finger are made of conductive material, so you can operate your smartphone while wearing the gloves. The wrist has a ribbed design to prevent cold air from entering. Usage Period: Worn for one season. I don't think there's much noticeable dirt.
