Our V series Mimic Hood is filled with Mimic Platinum, a high performance synthetic insulation. It also contains graphene to conduct your body heat and spread it throughout the garment. It's lined with a breathable fabric with superb moisture management properties. The surface is wind and water resistent and treated with a fluorocarbon free DWR to repel water and dirt. This combination enhances wearing comfort and gives the best warmth to weight – making this jacket ideal for cold mountain activities.
