When most women shop for sustainable underwear, the choice usually comes down to organic cotton vs. synthetic fabrics. Organic cotton is often seen as the eco-friendly option, while synthetics like polyester and nylon are known for stretch and durability. But the truth is, neither fabric is the best choice for comfort, performance, or sustainability.

At SUZI, we use Tanboocel™, a next-generation bamboo-based fabric, in all of our underwear because it outperforms both organic cotton and synthetics in every category that matters. Unlike ordinary bamboo fabrics (which are often just rayon), Tanboocel™ is made with a cleaner, modern process that reduces environmental impact while delivering premium softness and durability.

Softness, Stretch & Breathability

Women’s underwear made from Tanboocel™ feels silkier and softer than cotton from the very first wear. It has a natural stretch that cotton can’t provide, giving you a fit that moves with your body without the cling or static of synthetics. Even better, Tanboocel™ is naturally antimicrobial and breathable, which means it stays fresher longer and keeps you comfortable all day.

Better for You and the Planet

Unlike synthetic underwear, Tanboocel™ is plant-based and microplastic-free, so it won’t contribute to microfiber pollution in our oceans. Compared to organic cotton, Tanboocel™ is more durable and long-lasting, which means fewer replacements and less waste over time. Choosing Tanboocel™ underwear is not only better for your body — it’s also a smarter choice for the environment.

If you’ve been choosing between organic cotton underwear or synthetic underwear, you don’t have to compromise anymore. With Tanboocel™ women’s underwear, you get the perfect balance of sustainability, comfort, and performance — a fabric that truly feels as good as it is for the planet.
