All our suits are half-canvassed (Mohair).
We don't offer fused suits, nor full-canvas suits.
Fused suits: The canvas is glued to your suit's fabric. Most of the off-the-rack you can find in your local stores are fused suits.
Half-canvas: Some "fused" methods are still involved, but the canvas is sewed to your suit's chest.
Full-canvas: The entire structure of your jacket depends on its long canvas which covers almost the whole front of your jacket.
