Ergodyne Chill-Its® 6710 Evaporative Cooling Triangle Hat, Lime

It's so amazing to be able to cool down almost instantly

This triangle is a nice solution to have in the backpack. Not a place when its not in use and double effect when sunny. Sun on head protection and cooling.You lace it in a couple of seconds, no need of double knot. It was a doubt I had before testing it. A single one is enough for hours of hard work.This is also a solution that stays on the head without any of these annoying chin straps you can have on a hat. No move when wind blows or when you have your head down.The cooling effect is less efficient than on the evaporative towel of course as the material is thicker on this kind of product. Anyway, but this does the job and just need to be soaked more frequently.This triangle is a perfect complement to the towel when its really hot, real life approved.
