Reddit reviews TechNiche International Adult HyperKewl Cooling Sport Vest

Sure it is, just put on a cooling vest.

It gets pretty hot here in the summer time. When the temps are steadily above 100, I wear one of these under my mesh jacket. It absorbs a good amount of water that gradually evaporates over a period of time.

I’ve been riding continuously for the past 19 years, and off and on for 16 years prior to that. I’ve had a few close calls including going too hot into a corner and almost hitting a 4-Runner head on, target fixated on a barrier and scuffed the front tire on the edge for about 300 feet, rode on the gravel shoulder of an on-ramp because I misjudged the entrance speed and my ability, and got into a tankslapper for no explicable reason other than some Botts’ dots that may have upset the chassis.
As for crashes, I’ve had 2 other than a couple of minor drops: The first happened 5 years ago when a sanitation truck merged into me realizing he missed the weigh station and tried to get back on the freeway, had I been wearing over pants I would have walked away unscathed. The second incident happened in 2017 when the front end of my S1000RR gave way on a cloverleaf on-ramp I’ve traveled hundreds of times before for no reason (possibly spilled antifreeze because I was rolling on throttle when it happened). I was probably going 45 mph and walked away with a small scratch on my right arm where my jacket sleeve rolled up.
As others have pointed, good gear makes a difference, at a minimum I wear a Snell-rated helmet, gloves, a textile jacket, textile pants, and over the ankle boots. I live in hot, Southern California and when temps get over 85, I also wear a cooling vest which does a good job of keeping core temps down.
