A production-ready Seamless Circular Knit for Hoodies and Joggers, specified around warmth without bulk and a stable brushed surface. 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
Performance comes from three decisions: the yarn, the stitch and the finishing route. nylon spandex with silver ion filament supplies the base behaviour, a seamless circular knit sets how air and moisture move, and finishing is kept deliberately light so the attributes survive washing.

Performance features
- Compression: delivers graduated support while remaining easy to put on, measured by ASTM D2594 stretch and recovery.
- Hand and comfort: antibacterial performance that survives repeated home laundering.
- Construction benefit: tubular production that removes the side seam entirely.
- 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 Hoodies and Joggers, and suited to any programme where warmth without bulk and a stable brushed surface 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.
