Dutch denim brand G-Star Raw has teamed up with Pharrell Williams once again to deliver another collection of eco-friendly threads for Spring/Summer 2015.

Made in collaboration with Bionic Yarn, the Vortex Project, and Parley for the Oceans, this release was designed to raise awareness about ocean pollution through a full range of clothes constructed from recycled plastic bottles—ten tons to be exact.

Items like graphic tees, light outerwear, distressed jeans, and caps are presented in a muted color palette with maritime patterns and graphics featured throughout. This season, we see the return of Otto the Octopus as well as all-over water prints, which lend a lighthearted vibe to project that benefits a very serious cause.

Check out pieces from the “Raw for the Oceans” Spring/Summer 2015 collection below. The items will drop at select retailers beginning this month, followed by a second release in May.

To learn more about the collection and its purpose, head over to Raw for the Ocean’s website.
