88% Polyester 12% Spandex Four-Way Stretch Recovery Ponte Roma Knit is a firm ponte roma double knit developed for Sports Bras where controlled support and soft contact at the underband decides whether a style succeeds. The base is 88% polyester filament / 12% spandex, which gives the workhorse blend for training ranges that wash repeatedly. The result is a fabric that delivers Four-Way Stretch Recovery in daily use rather than only in a laboratory.

Why this construction works
The construction does the work before any chemistry is added. a firm ponte roma double knit means a clean, structured surface with enough hold for tailored athleisure, and that structure is what allows the fabric to extends in both directions and returns without bagging under the conditions Sports Bras actually face.

Recommended applications
The first choice for Sports Bras, where controlled support and soft contact at the underband is the requirement that decides the fabric. It also converts cleanly into coordinated pieces in the same programme, since the hand and the shade run together.

Frequently asked questions
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.
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.
