http://news.stanford.edu/news/2012/august/cooling-glove-research-082912.htmli came across this a while ago but it's still relevant. A cooling glove lowers core temperatures quickly, improving sports performance. The test subject was able to do eliminate muscular fatigue after sets of pullups.The reason it's a glove is that the hands have extensive networks of blood vessels near the surface of the skin which act as built in "radiators" when core temps are highThe reason to use a glove rather than dipping hands in ice water --the "radiators" activate only within a certain temperature range -- cool them too much too quickly and they vasoconstrict, therefore the glove cools but within the temperature sweet spot.The implication for climbing could be that if you could bring this to the crag you could recover quickly and fully between attempts.
so... bucket of ice water? about £10Also keeps your beer cold
It doesn't take a genius to work out why us bald blokes recover so quickly between attempts by simply managing our hat schedule

Studies have shown just cooling by itself doesn't offer any gains. Seems like some pretty legit science behind it and a decent amount of evidence showing performance gains - not another holographic bracelet. Ties in with another thread where people were talking about the causes of muscle fatigue and how it's now thought fatigue isn't caused by lactic buildup as previously believed.
