The construction does the work before any chemistry is added. a rib knit means high extension across the width with clean recovery, ideal for cuffs and bands, and that structure is what allows the fabric to extends in both directions and returns without bagging under the conditions Leggings actually face.

Frequently asked questions
Can we get recycled content with this construction? In most cases yes. GRS certified recycled nylon or polyester can replace the virgin yarn with full chain of custody documents, usually with no visible change in hand or performance.
Is the performance tested on every lot? Yes. The named test method is repeated on bulk fabric, not only on the approval sample, and the report carries the lot number so results can be traced back.
