Performance Wear’s Plastic Problem

Today's performance apparel uses tiny bits of plastic to achieve its strength, stretch and support. These yarns may be great for performance, but they bruise the environment.

3,500 trillion pieces of microplastics — weighing 3 million pounds — leak into our oceans every year from household laundry alone.

An additional 24 billion pounds of plastic from clothing alone ends up in landfills.

Both take centuries to biodegrade.

The Definite Way

We found a better way to make performance wear that doesn’t harm our planet.

We use a natural additive that makes the tiny plastic particles spun into our performance wear – all recycled, BPA-free and high-quality fit for human use – act like natural fibers.

That’s why the Definite sock sheds less plastic when washed and biodegrades far more quickly when discarded. So it will revert naturally to the earth.

Happy Feet. Happy Planet.

Regenerate

We may start small – our socks, your feet – but our mission is big: to help solve the planet’s plastic problem. Every pair of socks made transforms one plastic bottle back into soil.

Innovate

We turn the plastics in our yarns into biodegradable fibers while giving you all the qualities you want in a high-performance sock. Is that even possible? Yep, it is.
