Why you should care that your Summer hoodie is sustainable?

Like many industries, it turns out the fashion industry is destructive to our planet.

Did you know 2.1 billion tons of CO2 emissions are released each year in the fashion industry?1

Did you know the U.S. citizen reportedly throws away 70 pounds (31.75kg) of clothing and other textiles each year? 2

I could go on with horrific stats, but the point is it is probably time we started thinking about our purchasing choices.

There are a lot of brands out there to choose from, but we hope you will start supporting brands trying to make a positive impact on the planet, such as the sustainable hoodie brands listed in this article, because even small decisions can make a difference.
