Can anybody recommend one which is 100% reliable? I notice that the new Racing Jackets have such a system – is it possible to buy the arms separately and retro-fit them to Jawbones? I suppose a last resort would be to buy some Racing Jackets (can you get them frame only?) and use my prescription lenses in them – don’t really want to do that but then again that would be better than losing my Jawbone frame plus the lenses!

Anyone?

I use Windjackets. I don’t know if you could fit those legs?

Any of the end-on ones should work. I’ve used them for years on Twentys, Tens, Holbrooks and more for sailing.
