Recycled Materials

A work in progress, we’ve set a goal to work towards having a line completely made of only fully recycled fabrics in the near future. As we start this journey, our main goal is to do our part in reducing the industry’s greater impact one step at a time.

PFC Free DWR

As part of our commitment to improving our environmental footprint we have entirely switched from C6 DWR containing hazardous PFC’s (per- and poly-fluorinated chemicals) to PFC-free DWR on all our fabrics and styles that require a DWR coating. The importance of a cleaner textile process is fundamental in our journey to reducing our environmental footprint.
