The Chill-Its evaporative cooling hard hat headbands, from Ergodyne, easily attach to hard hat suspension headbands and come with hook-and-loop closure. Features lightweight, cooling acrylic polymers that activate in 2 to 5 minutes by soaking in water. Remains hydrated up to 4 hours. Simply re-soak to reuse. Blue. One size.
To activate, simply soak the Chill-Its bandana in ice water for 2-5 minutes, or until plump. Soaking the bandana too long will cause it to become over saturated and have a "slimy" feel. Product is not defective, it is simply over saturated. If it is over saturated, remove from the ice water and allow it to dehydrate. Once the bandana has dehydrated, it will no longer have the "slimy" feel, and can be used without further action.
