I just wanted to say a heartfelt "Bless You" to everyone here who has ever made or donated one of these!
When I was in a deployed location about two years ago, my unit got a box full of different morale things and there were some Cool Ties in the box. The guys I worked with didn't have a clue what they were about, but I grabbed about seven and took them out on the truck with us. A few hours later, after they'd been soaking in an ice cooler I handed them out and let me tell you, it feels SO GOOD when it it 130+ with humidity and you feel that coldness seeping in. So, serged, sewn, glued, they won't care, as long as they can make it cold!
You guys rock!
