What's Really In Your Underwear?

Over 65% of clothing today is made from synthetic fabrics (petroleum-based plastics like polyester). For underwear, it’s even worse.

These synthetic fibers don't breathe. They trap heat, moisture, and bacteria against your genitals for hours.

With every wash, they shed microplastics and release chemicals like BPAs, phthalates, and PFAS (forever chemicals). Endocrine disruptors linked to hormonal imbalance and fertility issues.

You wear underwear 16+ hours a day. Closer to your most sensitive skin than anything else.

Shouldn't it be made from something natural?

Why CEDR Exists

CEDR started with a simple frustration. Every pair of underwear on the market was either cheap and synthetic, or labeled premium but still blended with polyester.

We wanted something pure. Made entirely from natural fibers. No shortcuts. No compromises.

So we built it ourselves.
