Finding heavyweight wool
Heavyweight is a constraint on wool, not a separate fibre. Confirm it on the fabric page after you filter.

Marketplace check
Wool is filed here as protein fibre. One reason to open it is structure for tailoring and coats. One reason to sample is open weaves may need lining for opacity.
Judge heavyweight together with construction. Heavier cloths can overheat in warm climates or feel stiff if the silhouette wants fluidity.
What not to assume
A heavyweight filter does not certify the cloth. suits, jackets, coats are common places buyers test wool, and some of those garments will reject this attribute.
