OccuNomix Blue MiraCool Evaporative Cotton Cooling Hard Hat Pad,Navy

B07D59BW92 is a piece of cloth with cooling crystals inside that can be used to keep a hard hat wearer cool in hot weather. The product can be activated by soaking it in water for a short time and then wringing it out. It can remain cool for up to 8 hours and can be reactivated by re-soaking as needed. However, it is not fire retardant, and the crystals inside the pad hold water and keep the back cool. The product has received mixed reviews from customers. Some customers have found it to be effective in keeping them cool, particularly in dry heat. However, others have found that it dries up too quickly and absorbs sweat, making it less effective. Some customers have also found it too small for their hard hat or too heavy. However, some customers have recommended adding a fan inside the hard hat for a better cooling effect.
