T4 - what's the origin of your handle? Are you a microbiologist or biochemist?
I ask because long ago I did a bunch of research using bacteriophages, and it's odd to see the reference in this setting.
I've seen it used in a few expensive RTW suits (Brioni, Tom Ford), but never found one in the books. Looks fantastic, and I'd love to locate one.
If people are interested, there's a Tom Ford suit on display at BG (right next to the Marinella ties) that boasts this fabric.
