The Viking OLLI PRO girls’ mittens feature an Aqua Thermo Tex membrane paired with Thinsulate™ insulation, ensuring optimal thermal comfort. ThinsulateTM microfibres work on the principle of trapping air molecules - are very delicate, so the insulation is very light and at the same time traps much more air in less space than conventional fibres. The membrane provides wind and water protection, while at the same time wicking moisture away from the surface of the hand and helps keeping it dry The upper is made of a functional, durable Taslon polyester fabric. These mittens feature a convenient drawstring at the wrist, an elastic rubber cuff for a snug fit, and reflective elements for enhanced visibility.
