It’s forecast to hit 33°C here in London today, but we still wear full leathers. Dress for the slide, not just the ride.
As tempting as shorts and a t-shirt are in this heat, you just never know when you may have a spill. I have a friend who often recites stories of a stint they did as a nurse in A&E & theatres. Once putting a biker under a general aesthetic so they could use scrub all the grit out of his remaining skin after coming off with no decent gear on…
It may be hot and sweaty in gear, but I’d rather retain some skin through which I can sweat.
