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

Marketplace check
Poplin is filed here as plain weave. One reason to open it is clean surface for shirts and uniforms. One reason to sample is opacity varies with yarn and colour.
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. shirts, blouses, uniforms are common places buyers test poplin, and some of those garments will reject this attribute.
