IFR FR Cooling Hard Hat Liner & Neck Shade, Royal Blue - One Size Edge Eyewear two-layer knitting with wide foldedWhen soaked in water, the polymer crystals expand, and turn into a crystalline gel. The fabric absorbs water from the polymer, allowing the water to slowly evaporate for a cooling effect. The band stays cool and moist for hours due to the polymers water retaining properties and the slow evaporation rate. 1K 3K Microns water absorbing, non toxic polymer crystals Quick activation process when soaked in cold water Provides cooling relief from heat stress
