This would work. Efficient, effective, simple and cost effective application of cooling technology. Aide personnel would be able to change out the packets inside their PPE as needed, as well as, remove them when needed. What's interesting is that military and aid relief haven't yet invested in this technology. Cooling at the pulse points started a while back when a Stanford researcher circulated cold water through a glove to prolong the duration and intensity of exercise among a group of elite athletes. It's "cool" to see a company like Qore bringing pulse point technology to the general public. What's most desirable about a product like this for disaster response is in its simplicity of application - no training necessary, no external device needed, and no maintenance required in its operation. Just plug and play and save the world.
