Developed for Running Tops, this Spacer Knit answers the most common brief we receive: low weight with fast moisture transport. The yarn package is polyester elastane with a bio-based chitosan finish, chosen because it provides a bio-derived antibacterial route for restricted substance sensitive programmes, and the finished cloth is set and tested so that Compression.

Why this construction works
The construction does the work before any chemistry is added. a spacer knit with two faces means cushioning and airflow built into a single piece of fabric, and that structure is what allows the fabric to delivers graduated support while remaining easy to put on under the conditions Running Tops 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.
