Keep your hands warm, dry and visible with Occunomix Waterproof Winter Hi Vis Gloves. Constructed with Celliant® infrared fleece, a proprietary fiber incorporating thermo-reactive minerals. Recycling and converting escaping body heat into infrared energy, returning it back into the skin. The benefits are temperature regulation, reduced hand fatigue, and of course, warmer hands. Celliant technology lasts the lifetime of the material. It will never wash out or breakdown.
