I just rode for 1.5 hours yesterday when the temperature was a muggy, humid 35 (40 with the humidex) degrees celcius.
I was sweating like a pig the entire ride, hot as can be
I never felt like taking of my Roach DH Leg armour.
They aren’t that hot.
However, it sure feels nice to take them off after the ride, it’s like a burst of cool for your legs that you wouldn’t get if you didn’t have them on.
I give these 2 thumbs up
