74gsm polyester fine mesh. Heavier than the ultralight 30-40gsm options — more body, more structure. The mesh openings are fine and even — breathable, but not wide open. 163cm wide, a touch wider than standard, saving you fabric on larger cuts. 9 yards per kilo. Use it for activewear linings, pocket bags, laundry bags, ventilation panels, cap backing, craft projects. Breathable, stable, and sturdy enough to trust.
