Nontoxic Feminine Wash

CUFT® is redefining what clean underwear really means.

While most “clean” brands only focus on part of the garment, every inch of CUFT is made with 100% TENCEL™, a naturally soft, breathable, and biodegradable fabric derived from sustainably sourced wood pulp.

We’ve created a truly non-toxic underwear — from fabric to waistband — that’s completely free of PFAS, microplastics, and harsh dyes or chemicals.

No hidden synthetics. No compromises. Just comfort that’s as safe for your body as it is for the planet.

Most underwear is designed for durability using synthetic, plastic-based materials that never break down. CUFT® takes a different approach prioritizing non-toxic, plant-based materials that are safe for your body and can return to the earth at the end of their life.

CUFT® is made without synthetic fibers, elastane, or traditional plastic-based elastic. Even the waistband is made from a biodegradable TPU designed to break down over time, making the entire garment aligned with our plastic-free mission.

Our dyes are OEKO-TEX® certified and bluesign® approved, meaning they are tested and verified to be free from harmful substances such as:

• Azo dyes
• Heavy metals (lead, cadmium, chromium)
• Formaldehyde
• Phthalates

They are safe for sensitive skin and meet strict global safety standards.

Our underwear and camisoles are made from 100% TENCEL™, a wood-based, plant-derived fiber known for its breathability and softness. Unlike most underwear, which is made with synthetic materials (aka plastic), CUFT® is designed to be a lower-tox alternative that’s gentle on your body.

TENCEL™ fibers are produced using a closed-loop solvent spinning process. The non-toxic organic solvent is recovered and reused at a rate of over 99%, meaning it doesn’t remain in the final fiber.
