A production-ready Ponte Roma Knit for Sports Bras, specified around controlled support and soft contact at the underband. Composition is 50% polyester / 42% polyamide / 8% elastane, which delivers a dense surface that takes sublimation print cleanly. Every lot is finished and tested so that Four-Way Stretch Recovery is measurable rather than claimed.

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
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.
What is the minimum for a first order? Development starts at 300 metres per colour, which is enough for a proper wear trial and a small capsule. Bulk pricing improves at 1,000 metres and above per colour.
