Provided you live for motorcycle arcana, the Belstaff archive is an endlessly renewable resource. For Fall, designer Martin Cooper dove in and emerged with photos from what's known in the moto world as the ISDT: International Six Days Trial. The annual event is the oldest off-road motorcycle competition in the world, and the 1965 edition, held on the Isle of Man, is, according to Cooper, widely considered to be the pinnacle of British motor sports. (Germany took the trophies that year, but never mind.)

A poncho worn by one of the ISDT riders became the waxed poncho in the new collection. From there, Cooper let his imagination whir. The Roadmaster and Trialmaster jackets are waxed-cotton classics for Belstaff. To them, Cooper added the Sportmaster, a four-pocket version that came as a "modular" jacket (meaning its quilted lining is removable) in waxed cotton and hybrid cotton-tweed versions, and also as a sleeveless gilet. (The advantage being that this one shows off the Belstaff knitwear underneath.) New as well were the introduction of a cargo trouser in leather and in waxed cotton, and a selection of gorgeous woolly shearlings, hand-rubbed for a patina like a favorite chair—which, if you are the target audience, is likely a bike seat.
