YES! - These are the ones that plump up when you soak them in water. The Original MiraCool! As the water evaporates throughout the day, it gives you a nice cooling effect.
These also plump when you soak them like the original MiraCool Crystals but not as much. They also activate much faster.
Super absorbent, durable, lightweight material. Works with water or just wicking.
Chemical-Free Cooling™ fabric technology - Wicks and cools - with or without water
Cooling effect lasts for hours maintaining a constant temperature of 65° Fahrenheit for consistent cooling. These do not reply on evaporation to cool so they can be worn over or under other garments. They also work well in humidity where evaporation is hampered.
