Cooling vests

Hi Folks,

Any advice or recommendations out there on cooling vests. I don't want one of those that you soak, wring out and wear yuk...

 

LoL. Unfortunately where I work and ride my bike in the Central Asian mountains, I don't have the luxury of being able to order stuff on the internet and having it delivered the following day or simply riding down to my local bike bits shop and buying what I want. That's why I'm asking the question now so that I can garner advice and get it ordered now so that I might just have a chance of receiving it as summer here commences...

 

BTW we've had snow here constantly for the past three months with still over a foot on the ground so we don't have even the option to wear heated kit... :-(
