OUR COMMITMENTS

What is Organic Cotton?

Organic cotton is cotton that’s grown without harmful chemicals like synthetic pesticides or fertilizers. Instead, it uses natural methods to protect the soil, support biodiversity, and reduce water pollution.

Unlike conventional cotton, organic cotton is often gentler on the environment and safer for farmers and wearers, especially those with sensitive skin. It’s also usually processed without toxic dyes or bleaches, making it a more sustainable and conscious choice in fashion.

What is Recycled Polyester?

Recycled polyester is a fabric made by repurposing used plastic, like water bottles or fabric scraps, instead of creating new plastic.

The plastic is cleaned, melted down, and spun into new fibers, which are then woven into fabric. This process helps reduce waste, save energy, and by reusing existing resources, we significantly lower our environmental impact. Saving an average of 90% water and 80% CO₂ compared to traditional production methods.

How are your products sustainable?

Our clothes are eco-friendly because we prioritize sustainability at every stage of production. We use natural fibers that are grown without harmful pesticides or chemicals, which helps protect the environment and the farmers who grow them. By using recycled materials, we help reduce waste and the need for new resources, cutting down on pollution and energy consumption.

Each item is made to order, which minimizes waste and supports a more sustainable fashion model by ensuring that no excess inventory is created. Our manufacturing processes are designed to be as responsible as possible, ensuring minimal impact on the planet while creating high-quality, long-lasting garments.

Our certificates


Is your packaging also eco-responsible?

We use POLLAST!C mailers made from certified Ocean Bound Plastic collected from coastal areas at risk of pollution. They have one of the lowest carbon footprints available — 75% lower than traditional plastic and 30% lower than recycled paper. Fully recyclable with soft plastics or reusable thanks to a second seal, they’re a smart, eco-friendly choice.

Each item is also carefully inspected before shipping to reduce returns and unnecessary emissions. A detailed size guide is provided to help you choose the right fit and support more sustainable shopping.
