Developed for Yoga Sets, this Seamless Circular Knit answers the most common brief we receive: a soft hand with modest, sustained stretch. The yarn package is nylon spandex with silver ion filament, chosen because it provides antibacterial performance that survives repeated home laundering, 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 Yoga Sets actually face.

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.
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.
