This is an extra layer, but been using it for years now.
Extremely well made, adjustable in size and does not flap about AT ALL. It has a few pockets as well.
As for a jacket i'd suggest going on the J&S website the locate your nearest store to start trying some on.
Was there supposed to be a link there.
I am happy with my high vis, its a stretch running top that is a very good fit. I have been in J&S and tried some on.
Being out of the EU will actually make it easier to make our own laws, I ask because while looking for a jacket I am seeing more and more with flashes of high vis, thinking about it some hi vis armbands would do the trick and not be an extra layer if the law changed.
I wonder though if that would mean that the jacket would have to be classed as safety wear and so zero rated VAT, dont think the government would shoot themselves in the foot on that one just for the sake of a few biker lives.
