Finding soft denim
Soft is a constraint on denim, not a separate fibre. Confirm it on the fabric page after you filter.

Marketplace check
Denim is filed here as cotton twill family. One reason to open it is durable twill structure when correctly specified. One reason to sample is stretch and recovery must be verified for fitted jeans.
Judge soft together with construction. Very soft cloths may crease more or lose crisp structure needed for formal shirts.
What not to assume
A soft filter does not certify the cloth. trousers, jackets, workwear are common places buyers test denim, and some of those garments will reject this attribute.
Questions
