The accessory no fund manager should be without.
In fairness from that video it appears to be well thought out and with the collar folded down it would probably look OK (those pics aren't representative), perhaps good. However, I can't stand the posh leanings of the Brompton company, and when I hear the god-awful accents and double-barreled names of the new company heads, well, it's skin-crawl-inducing.
