Finding opaque canvas
Opaque is a constraint on canvas, not a separate fibre. Confirm it on the fabric page after you filter.

Marketplace check
Canvas is filed here as dense woven. One reason to open it is structure and durability. One reason to sample is confirm weight for wearable programmes.
Judge opaque together with construction. Higher opacity can add weight or reduce breathability.
What not to assume
A opaque filter does not certify the cloth. workwear, jackets, trousers are common places buyers test canvas, and some of those garments will reject this attribute.
Questions
- Does opaque canvas mean every listing qualifies?
- No. Open the fabric page. If the spec does not support the attribute, drop the card.
