Polyester Spandex Bamboo Charcoal Breathable Mesh Spacer Knit is a spacer knit with two faces developed for Sports Bras where controlled support and soft contact at the underband decides whether a style succeeds. The base is polyester spandex with charcoal loaded filament, which gives permanent odour adsorption built into the yarn rather than the finish. The result is a fabric that delivers Breathable Mesh in daily use rather than only in a laboratory.

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 keeps air moving across the skin in high heat zones under the conditions Sports Bras actually face.

Performance features
- Breathable Mesh: keeps air moving across the skin in high heat zones, measured by ISO 11092 thermal and water vapour resistance.
- Hand and comfort: permanent odour adsorption built into the yarn rather than the finish.
- 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 Sports Bras, where controlled support and soft contact at the underband 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.

Breathable Mesh fabric prepared for Sports Bras production
Dyeing, finishing and customisation
Available in piece dyed, yarn dyed or sublimation ready form. Functional finishes such as moisture management, antibacterial, anti-pilling and UV absorption can be applied individually or combined, and each is verified against its test method before bulk release.
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
Trial quantity starts at 300 metres per colour with laboratory dips in five working days. Bulk lead time is 20-25 days after approval, and every lot ships with a test report, a shade check and an inspection record.

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.
