The Nebula Mitts are insulated mitts, made using innovative Cirrus™ synthetic insulation to offer low-bulk warmth for use in very cold and damp conditions. The Nebula Mitts are designed with a water-resistant Pertex® Endurance outer fabric, which supports the Cirrus™ insulation inside. Cirrus™, powered by 3M Featherless insulation, is an innovative new approach to synthetic insulation, combining all the key benefits of both natural down and synthetic insulation, whilst avoiding their limitations. The Nebula Mitts also feature a pebble fleece lining, 70d Nylon reinforcements in high wear areas and a textured grip palm. These features lend the Nebula Mitts to big mountain mountaineering and polar travel in the harshest, and potentially dampest environments in the world.
