Full-Canvas vs. Fused Construction
The hidden skeleton inside your jacket decides whether it drapes or dies.

What even IS a canvas?
The canvas is an internal layer — horsehair and wool — sewn between the outer fabric and the lining of a jacket's chest and front. It's not glue. It's a structural membrane hand-stitched to the shell so the two layers move together. Think of it as the jacket's spine. Without it, you just have two pieces of fabric loosely related to each other.
Fused is just cheaper, right?
Correct, but the mechanism matters. Fused construction bonds the chest piece to the shell using heat-activated adhesive — same basic idea as ironing on a patch. Savile Row moved to pure canvas construction in the early 20th century. Fusing went mass-market in the 1960s when the men's suit industry industrialized. Speed tripled, cost dropped, quality followed. Most suits under $800 today are fully fused.
