Cooler heads pre­vail

Los Angeles Times - - TRAVEL - — Judi Dash

The “air-con­di­tion­ing” tech­nol­ogy be­hind Real X Gear’s Cool­ing Caps and Vi­sors is as ba­sic as this: Wet it, wear it, and let good old evap­o­ra­tion do the cool­ing. The trick is in ex­tend­ing the cool­ing evap­o­ra­tion time as long as pos­si­ble. The head­band area of RealX Gear’s head wear is lined with a strip of ab­sorbent and wa­ter-re­tain­ing fab­ric called Poly-Vinyl Al­co­hol. Em­bed­ded al­co­hol beads chem­i­cally re­act with wa­ter to lower the tem­per­a­ture of the ma­te­rial and slow the dry­ing process. This may sound way too lowtech to be any­more ef­fec­tive than dunk­ing any old hat, but a test run on a re­cent hot sum­mer day showed Real X Gear’s caps and vi­sors do in­deed stay cooler sub­stan­tially longer than stan­dard head wear. Keep an ex­tra “wet” cap or vi­sor in a cooler to switch off when your head wear runs out of cool. The caps and vi­sors come in blue, black, white, cam­ou­flage, khaki, red or pink. Caps or cool­ing vi­sors cost $20. Info:­fVTb.
