ethical, sustainable manufacturing

At Thinx, we craft our underwear carefully and consciously. From sustainable manufacturing processes to ethical working conditions, we ensure that every pair is made with mindfulness and dignity.

Our eco-friendly partner

We’re proud to work with MAS, a global leader in ethical manufacturing based in Sri Lanka. MAS promotes environmental sustainability and has high goals for zero-waste production. They’re committed to sustainable systemic change and have implemented strong criteria to reach these goals by 2025!

MAS operates under three pillars:

  • Products changed for good

    By working with MAS, they’re helping us create more sustainable, longer-lasting products from natural raw materials that can be recycled at the end of their lifespan! Their facility also focuses on upcycling any fabric waste into new products.

  • our planet changed for good

    99% of MAS' waste is diverted away from landfills, and they are committed to value-enhancing 100% of their non-hazardous waste. MAS has safe chemical management practices to reduce human and environmental impact, and they're also committed to working on reducing water usage and factory emissions.

  • Lives changed for good

    MAS is a world-class workplace that helps their employees thrive. They prioritize diversity, inclusion, well-being, fair pay, and performance-based recognition — and also have programs like Women Go Beyond, which creates opportunities for women.

intentional about our fiber choices

Our product range is made up of a number of fibers, such as Supima® Cotton, Tencel™ Modal, polyester, and nylon.

We need our underwear to uphold our strict criteria for comfort, absorbency, and wearability, and we are continually researching sustainable materials that meet those standards.
Thinx - Manufacturing - intentional about our fibers

Our signature Modal Cotton blend is made using materials that have a positive impact on the environment.

We are in the process of researching more sustainable alternatives to traditional polyester and nylon for our product range and look forward to rolling these out when we have the right fit.
