Canvassing is a form of interlining where a layer of fabric, usually linen or horse hair, is sewn into the jacket. HARTTER | MANLY does not use fused linings that are typically found in retail stores. Fused linings are cheap and easy to produce, which largely lowers the cost. Our entry level suits are half-canvassed and use canvas on the chest, lapel, and down to the pocket, with the lower half of the jacket being fused. Full-canvassed suits use canvas through the entire front of the jacket allowing the jacket to move and shift with your body. The more you wear it, the better it will fit as it begins to mold to your shape.
