Our story
Why we exist
Most underwear is made from petroleum-based synthetics that shed microplastics with every wash and take centuries to decompose. Even the brands marketing themselves as sustainable still rely on conventional elastane — the same plastic, just wrapped in better storytelling.
We started Naked Grain to solve the whole problem, not just the visible parts.
It began with a question about what we put closest to our skin every day, and whether the materials we accept as normal are ones we'd actually choose if we understood them. The answer, for us, was no.
So we built something different. We sourced ethically sourced (mulesing-free) merino wool for natural thermoregulation and odor resistance. TENCEL™ Lyocell from sustainably managed forests for a hand feel closer to silk than cotton. And Roica V550 — a stretch fiber developed by Asahi Kasei in Japan that biodegrades to CO₂ and water, certified Cradle to Cradle Material Health Gold. Most of the industry doesn't even know it exists yet.
Then we engineered the construction to match the materials — 3D shaped pouch, tubular knit body with zero side seams, flat-lock stitching throughout. Because choosing better materials means nothing if the garment doesn't perform.
The result is premium underwear where every fiber is biodegradable. No microplastics in your wash. No compromise in your comfort. Nothing left behind when it's done.
