In the realm of fashion—a multi-billion-dollar titan of industry known for its lucrative returns—lies an inconvenient truth: it ranks as the second-largest polluter worldwide, trailing only behind the oil sector.

The core of most activewear, a blend of polyester or polyamide/nylon with elastic fibers like elastane, spandex, or Lycra, offers the ideal moisture-wicking properties for high-intensity and physically demanding activities. Yet, the synthetic fibers at the heart of these garments, derived from fossil fuels, are significant contributors to greenhouse gas emissions.

Positioned at the forefront of the activewear and athleisure fashion wholesale market, Mono B acknowledges the gravity of this environmental impact and embraces the challenge with resolve. Eschewing the conventional route of using virgin polyester or nylon, we turn to an innovative solution: recycling discarded polyethylene terephthalate (PET) bottles and post-industrial or pre-consumer nylon scraps. This process breathes new life into these materials, crafting them into our pioneering Mono B GREEN line—a testament to our commitment to sustainability without compromising quality.


We've sourced our 100% recycled polyester from Jiaren, one of the few companies in the world able to infinitely recycle polyester fiber without causing the loss of quality by using ECO-CIRCLE™ technology.

Our 100% recycled nylon fibers are GREENLON® nylon yarns that save energy up to 8.5% and water up to 84%, whilst reducing up to 77% of CO2 emission.

The result is Mono B GREEN, a sustainable, earth-friendly collection, without compromising Mono B's hallmark high-quality and affordability.
