Finding lightweight twill
Lightweight is a constraint on twill, not a separate fibre. Confirm it on the fabric page after you filter.

Twill is filed here as diagonal weave. One reason to open it is flexible fibre platforms. One reason to sample is fibre still decides care and seasonality.
Judge lightweight together with construction. Very light cloths may lose opacity or structure. Confirm silhouette support and lining needs.
What not to assume
A lightweight filter does not certify the cloth. trousers, jackets, uniforms are common places buyers test twill, and some of those garments will reject this attribute.
