Belstaff Trialmaster Jacket in Blue. The Trialmaster has earned its place as a part of Belstaffs legacy, with a regular fit silhouette. The jacket is usually crafted from waxed cotton, however this season the brand have replaced the usual material with a water-repellent poly outer for functionality. Other features include a two-way zip fastening with an added popper placket for security and an internal drawstring to the waist. Four pockets are featured to the front, with signature Belstaff branding to the sleeve on a leather patch for a luxe finish.
