The sustainable shoe brand Allbirds is debuting a collection of activewear, making it the latest entrant into a hotly competitive category.
With Allbirds, reducing carbon emissions and being environmentally friendly is a top priority. The retailer has avoided using polyester, which it says makes up 55% of all clothing and spews 700 million tons of carbon into the atmosphere each year. Instead, Allbirds has created the running clothes with eucalyptus tree fiber and merino wool — two materials that go into its iconic slip-on sneakers.
Allbirds said it has worked on the collection for more than two years, with over 70 iterations.CNBC
