Finding breathable rayon
Breathable is a constraint on rayon, not a separate fibre. Confirm it on the fabric page after you filter.

Marketplace check
Rayon is filed here as regenerated cellulose. One reason to open it is useful for fluid dresses and blouses. One reason to sample is care and shrinkage need sampling.
Judge breathable together with construction. More open structures can reduce opacity or wind resistance.
What not to assume
A breathable filter does not certify the cloth. dresses, blouses, linings are common places buyers test rayon, and some of those garments will reject this attribute.
Questions
- Does breathable rayon mean every listing qualifies?
