I use the CoolAir system for sanding and sweeping in my workshop, and it’s been a game-changer. Super lightweight, easy to wear all day, and I don’t feel overheated like I did with other gear.
It's nice it works excellent and it works for two and a half to 3 days straight like it said but I have to leave it in the freezer longer than 20 minutes for it to add the extra few hours to it of coldness
