I have extensively described my enthusiasm about a cooling vest (see older blogpost).
Yesterday evening I have tested a
cooling baseball cap from the company Cooline
www.e-cooline.de
Actually unbelievable, but you are sitting with a black cap in the sun at 28°C in the shade with your head being cooled.
“Only” water is put on this cap, like on the vest, about 0,3 liter. The fleece on the inside of the cap absorbs the water, and the cap virtually sweats and cools.
Ingenious!!!
Unfortunately my match was cancelled, I forgot my tennis shoes.
