Not looked at the vid,
But I only wear leathers.With armour.
I have a Richa gortex jacket I got for downpour rides and every time I rode in it I felt exposed.
It lives on a hook in my hall now and if it starts to rain I stop and get my waterproofs out of my engine bar bags.
Might be fine,,,,,,,,,,,might not.
I was at my brothers bedside when they got the gravel out of his thigh after getting knocked off, with a toothbrush and no anesthetic due his allergies/fits.....not something I want to see again,
Also..leathers are quieter, they don't flap.
Touching my wooden desk........brrrh
