A production-ready Rib Knit for Sports Bras, specified around controlled support and soft contact at the underband. Composition is nylon spandex with silver ion filament, which delivers antibacterial performance that survives repeated home laundering. Every lot is finished and tested so that Compression is measurable rather than claimed.

Why this construction works
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 delivers graduated support while remaining easy to put on 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 the weight and width be changed? Yes. Most programmes run between 140 and 340 GSM, and width can be set between 150 and 180 cm to match your marker. Changing weight changes cover and stretch, so we re-test before confirming.
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.
