Sustainable fashion is reshaping the industry as consumers demand eco-friendly alternatives to fast fashion. In 2025, startups are leading the charge by innovating with sustainable materials that reduce environmental impact without sacrificing style. Here are the top five fashion startups using sustainable materials, driving a greener future.
Why Sustainable Materials Matter
The fashion industry accounts for about 10% of global carbon emissions, with traditional materials like cotton and polyester taxing resources heavily. Startups are tackling this by using recycled, bio-based, and low-impact fabrics, cutting waste and pollution while meeting the growing demand for ethical clothing.

Based in Oakland, California, they use sustainable materials like organic cotton and recycled fibers. In 2025, Unspun is scaling its micro-factories globally, reducing shipping emissions and bringing production closer to consumers. Their innovative approach earned them a $32 million funding round in 2024.
2. Pangaia
Pangaia, a London-based brand, blends science and style, using bio-based materials like seaweed fiber, eucalyptus pulp, and recycled cotton. Their vibrant activewear and essentials prioritize closed-loop systems, encouraging garment recycling.
