Outerknown + Econyl®

Turning Waste Into Jackets, Boardshorts, and More

Our collaboration with ECONYL® aims to make the apparel industry’s production cycle more responsible. ECONYL® is developed from 100% regenerated nylon materials, including abandoned fishing nets and other pre-and post-consumer waste which we use in our Evolution Series of jackets and boardshorts. And the best part is that we get to help clean up the ocean and reduce our environmental impact.
