The Purarium Standard
Every brand claims to be clean. We put it in writing.
The Purarium Standard is the single filter every product must pass before it carries our name. No exceptions.
───
What We Use
GOTS-Certified Organic Cotton
Grown without synthetic pesticides or fertilizers. Certified at every step of the supply chain — from farm to finished garment.
Tencel / Lyocell
Derived from sustainably sourced wood pulp. Exceptionally soft, naturally moisture-wicking, biodegradable.
Bamboo
Naturally antibacterial and moisture-wicking. No synthetic finishing treatments.
Merino Wool
Temperature-regulating, naturally odor-resistant. Performs better than most synthetics without a single microplastic fiber.
OEKO-TEX Standard 100 Certified Materials
Independently tested for harmful substances. Every component — fabric, thread, label, dye — must pass.
───
What We Never Use
Polyester & Nylon
Synthetic plastics that shed microplastics with every wear and every wash. Off the list entirely.
Synthetic Elastane / Spandex
Petroleum-derived stretch fiber found in virtually every conventional legging. We use natural alternatives only.
PFAS / Forever Chemicals
Used industry-wide for moisture-wicking and stain resistance. Linked to hormonal disruption and metabolic issues. Never used in any Purarium product.
Synthetic Dyes Containing Heavy Metals
We use only low-impact, OEKO-TEX certified dyes. Nothing that doesn't belong near your body.
Plastic Packaging
No poly mailers, no synthetic wrapping. Every order ships plastic-free.

Why It Matters
Your skin is your largest organ. During exercise — when your body is warm, your pores are open, and your blood flow is elevated — it absorbs what it comes into contact with more readily than at any other time.
Conventional activewear is made from wearable plastic. We made a different choice.
The Purarium Standard exists so you never have to research us. Buy anything with our name on it and you already know what's in it — and what isn't.
Pure by design. Protect your biology.
