2021 marked the first time in the brand's history that we could introduce full lines of mens and womens apparel, which happened in Q4. Building on the foundational elements of 2020, we continued to deepen the penetration of sustainble materials across all products and packaging. We also added another sustainable India-based supplier specialized in organic fibers and OEKO-TEX processes. On the supply side we now have a range of super accomplished partners who have the depth to handle more complex products and the breadth to scale alongside us.

On the other hand, 2021 also meant supply chain challenges across the globe, which complicated the timing of some of our rollouts. For example, we ended up having to use regular plastic polybags for our socks because we could not get the NoIssue compostable ones in time. And, while we had ordered most products with enough lead time to make key selling seasons via ocean freight, we ended up air freighting more product during Q4 to hit the launch deadlines themselves. We will push to avoid this in the future as best we can.

All in all, I am pleased to have stayed the course for the major products, and outside of accessories we continued growth in eco-friendly penetration to reach every single product. Continuing the Sustainability Scorecard approach from 2020, I'm now providing below updated numbers according to each product line based on total units produced during 2021. The breakout is also adjusted to show mens, womens, accessories (water bottles, hats, socks), and masks.

Once again, let me say that this scorecard is a simple measure. It is based on the eco-friendly ratings (from 0% to 100%) we assign to individual elements in products, processes, and packaging. For example, 100% organic cotton fabric is rated 100% while our bamboo is rated 40%, and regular polyester is 0%. The chart above shows how these measures reflect proportionally according to total units produced in 2020. For example referring to hats, 90% of these products were fully eco-friendly in terms of materials, 80% used compostable packaging, and 10% of the process was sustainable.
