  • 1. Buy a shipping label
  • 2. Mail your retired Aero Zeroº back to us
  • 3. We recycle it into a brand new Aero Zeroº

Aero Zero in Leaves

Zero Footprint

Since 2019, we've been making Aero Zeroº shirts from upcycled PET water bottles and milling our fabric under renewable solar power, allowing us to reduce carbon emissions by over 50%. The emissions that we we aren't able to eliminate are offset, creating the first 100% recycled, carbon-neutral dress shirt.

Now, we're taking things a step further.

Process of Infinity

Infinite Use

Our shirts are built and tested to last, but when you're ready to retire your Aero Zeroº we can give them a new life. Working with our partners at Shinkong Textiles, we've developed a revolutionary hybrid mechanical-and-chemical recycling process that can separate polyester fibers. We then re-spin it back into yarn that's just as strong, durable and soft as before, creating the world's first circular dress shirt.

Fashion has a sustainbiltiy problem.

Why Infinityº Matters


of global greenhouse gas emissions come from apparel & footwear production


of apparel is incinerated, downcycled or disposed of in landfills


of performance fabrics' carbon emissions come from petroleum drilling and refining

We believe that through materials science and smart supply chains, there's a better way.


Half the Emissions

The Infinityº Program was optimized to reduce greenhouse gas emissions. Durable recycled material, solar powered-milling and quick-dry fabric results in a garment that has 1/2 the carbon emissions of conventional shirts.

Why Run a Half-Marathon?

Another route to achieving this sort of positive impact would be to run 13.1 miles instead of driving. (We've done it, but you don't have to.) Infinityº is a simpler choice.
