The difference you feel

Natural Is The Standard

Natural fiber works the way your body does. It breathes, moves moisture away, and regulates temperature on its own, with no chemical finish doing the job for it. That is the whole reason we build from fiber instead of plastic.

Every Fiber Clears The Same Bar

A natural label is easy to claim. These are the rules every CEDR garment is held to before it earns its place in the range.

  1. 100% Natural Fiber, In Every Product

    No polyester, no nylon, no spandex. If a fiber is not grown, it does not go in.

  2. Tested Safe To The Strictest Grade

    Every material meets OEKO-TEX Standard 100, Class I, the same tier used for products made for babies.

  3. No Forever Chemicals

    No PFAS, no synthetic water or stain finishes, nothing engineered to never break down.

  4. Independently Certified, Never Self-Declared

    Every claim we make is backed by a third party, audited by someone other than us.

  5. Honest About Every Fiber

    We tell you what each fabric is, where it comes from, and why we chose it.

The Standards Behind Every Piece

A natural label means nothing without proof. These are the independent standards our fibers, and our packaging are held to.

Responsible Wool Standard

RWS / Textile Exchange / v2.2

Wool from non-mulesed sheep on welfare-audited farms, with land management that protects soil and biodiversity, and a tracked chain of custody from farm to finished garment.

Global Organic Textile Standard

GOTS / v7.0

Certified organic fiber, traceable and audited at every stage, with a ban on toxic chemical inputs across the whole supply chain and social criteria protecting the people who make the cloth.

European Flax

Alliance for European Flax-Linen & Hemp

Flax grown in Western Europe and traced back to the field, rain-fed with no irrigation and no GMO, from a zero-waste plant where every part is used.

OEKO-TEX Standard 100

Class I / Strictest tier

Every component tested for harmful substances, thread and trims included, at Class I, the same grade applied to products for babies. Re-tested and re-certified, never a one-time check.

FSC Certified Packaging

Forest Stewardship Council / Mix

Greyboard boxes and paper stickers, fully plastic-free, with paper sourced from responsibly managed forests and recyclable with the product inside.

Natural Rubber Waistband

CEDR Material Standard

Natural latex rubber in place of synthetic elastane, the part that started CEDR, held to the same no-plastic rule. Soft, recovering stretch with nothing petroleum-based against the skin.

Corn Fiber

CEDR Material Standard

Plant-based fiber spun from corn in place of synthetic stretch, used where a garment needs give without reaching for plastic, and renewable at the source.
