When 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 fabric stays cool and moist for hours due to the polymer’s
water-retaining properties and the slow evaporation rate.**Polymer crystals only in the hard hat liner
