Can't comment on that one but the best reflective gilets I've come across are raceviz. They meet the standards (at least the Dark Jacket and one of two others do) and are cut like normal cycling gilets. I've got a Rysy which is pretty good. My only issue is that it isn't fully windproof, but that seems to be the type of fabric they use to take the reflective bits.
This is their UK seller https://wowowuk.net/product-category/raceviz/
