Developed for Tennis and Golf Wear, this Seamless Circular Knit answers the most common brief we receive: sun protection with a clean, structured appearance. The yarn package is nylon spandex with copper bearing filament, chosen because it provides antibacterial action plus faster heat transfer away from the skin, and the finished cloth is set and tested so that Four-Way Stretch Recovery.

Why this construction works
The construction does the work before any chemistry is added. a seamless circular knit means tubular production that removes the side seam entirely, and that structure is what allows the fabric to extends in both directions and returns without bagging under the conditions Tennis and Golf Wear actually face.

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 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.
