Women's - Trialmaster Waxed Cotton Jacket - Forest Green
Originally crafted for the iconic Scottish Six Days Trial, the Trialmaster has been Belstaff’s signature jacket since 1948. This latest version is made from British Millerain 8oz ultracore waxed cotton in Black and features an updated sleeve design for greater freedom of movement. The jacket blends classic style with modern functionality, offering D3O shoulder and elbow armour for reliable protection while maintaining its timeless details, such as the slanted map pocket and heritage check lining.
With a hand-waxed finish, inter-layered waterproof membrane, and reinforced patches on the shoulders and elbows, it’s built to handle both the road and the elements. Metal under-arm vents ensure breathability, while the four-pocket design with waterproof flaps and press-stud closures adds practical storage. Corduroy trim on the collar and cuffs and a buckle cover with the embroidered Belstaff logo complete the look.
