I was looking into gear to get as a new rider and came across this video. I’ve seen some of his videos before and his argument seems reasonable.

Those of you who agree, what would you recommend for leather jackets and riding pants?

Those of you who disagree, what body armor do you recommend?

I’m curious to hear both sides of the argument, I think there’s evidence to support either side. Thanks!
