A production-ready Single Jersey Knit for Running Tops, specified around low weight with fast moisture transport. Composition is 78% GRS recycled nylon / 22% spandex, which delivers virgin nylon performance with a documented recycled content claim. Every lot is finished and tested so that UPF 50+ Sun Protection is measurable rather than claimed.

Why this construction works
Performance comes from three decisions: the yarn, the stitch and the finishing route. 78% GRS recycled nylon / 22% spandex supplies the base behaviour, a plain single-bed knit sets how air and moisture move, and finishing is kept deliberately light so the attributes survive washing.

Performance features
- UPF 50+ Sun Protection: blocks ultraviolet radiation for outdoor training, measured by AATCC 183 ultraviolet transmittance.
- Hand and comfort: virgin nylon performance with a documented recycled content claim.
- Construction benefit: the lightest way to get coverage, with good stretch and a clean surface for printing.
- Consistency: GSM and width tolerance are locked per lot and recorded on the inspection sheet.
- Durability: performance is verified after repeated washing, not only as delivered.
Recommended applications
Specified mainly for Running Tops, and suited to any programme where low weight with fast moisture transport is written into the brief. Designers use the same base for matching styles, which keeps colour continuity simple across a collection.

Dyeing, finishing and customisation
Dyeing runs on a controlled recipe with consolidated dye lots to hold shade continuity. Finishing options include wicking, antibacterial, soft touch and anti-pilling, applied after lab trials so the hand approved in sampling is the hand delivered in bulk.
Care instructions
- Machine wash at 30 degrees with mild detergent, no fabric softener.
- Dry away from direct heat and do not tumble dry hot.
- Cool iron on the reverse if needed, and avoid bleach.
Ordering, sampling and quality control
Sampling is fast: A4 hand feel cards, laboratory dips and a 5 metre trial roll within a week. Bulk runs in 20-25 days, with inline inspection and a final random inspection before packing.

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.
