Does the CF use Cooling Vests?

The under armour Cooling vests with the the Ice packs you insert, I had one after 3 hrs you need to find a Freezer :, I have the USMC type its a Mesh that provides air pockets for circulation and works much better.

Wouldn't be much of a cooling vest as in CF use, but more of a air circulation aid. Most COTS packs have this technology, doesn't do too much when its saturated with sweat already.
