A production-ready Spacer Knit for Leggings, specified around squat-proof coverage and recovery at the knee and seat. Composition is polyester elastane with a bio-based chitosan finish, which delivers a bio-derived antibacterial route for restricted substance sensitive programmes. Every lot is finished and tested so that Compression is measurable rather than claimed.

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 Leggings actually face.

Performance features
- Compression: delivers graduated support while remaining easy to put on, measured by ASTM D2594 stretch and recovery.
- Hand and comfort: a bio-derived antibacterial route for restricted substance sensitive programmes.
- Construction benefit: cushioning and airflow built into a single piece of fabric.
- 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
The first choice for Leggings, where squat-proof coverage and recovery at the knee and seat is the requirement that decides the fabric. It also converts cleanly into coordinated pieces in the same programme, since the hand and the shade run together.

Frequently asked questions
What is the minimum for a first order? Development starts at 300 metres per colour, which is enough for a proper wear trial and a small capsule. Bulk pricing improves at 1,000 metres and above per colour.
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.
