2012 edition of the John Boultbee collection of cycling jackets designed by Timothy Everest :
Introducing the Elder Street MK1.
“The casual Elder Street blazer is made from Fox Brothers tweed (a Savile Row textile supplier for some time) which has been specially treated to make the fabric water repellant.
Shaped sleeves cut for cycling, an angle storm welt back pocket, a reflective Boultbee strap on the underside, 6mm topstitching…”
Not really sure of this style mix (details etc.) but would be interesting to see it for real.
