Recycled Ocean Crochet

The Sak is committed to reversing the tides of plastic in the ocean. In partnership with Oceanworks®, we created our Recycled Ocean Crochet yarn sourced from ocean recycled fishing nets. This yarn is used in all of our ReSak collection. 


Plastic waste in our oceans is devastating to marine ecosystems. While there is a concerted effort to remove this waste directly from the water, these initiatives are only part of the battle. Researchers have found that plastic waste within 30 miles of the coastline is most at risk of eventually ending up in the ocean. This waste is termed “ocean-bound plastic” and diverting it is a crucial step in reducing ocean pollution. Learn more about ocean bound plastics here. The crochet yarn used all of our customized crochet products is created from recycled ocean bound plastic.

Leather Working Group

Leather Working Group's mission is to improve the environmental impact of the leather industry by assessing and certifying leather manufacturers. It aims to engage with members of the leather supply chain and give them the knowledge to be able to make informed, sustainable choices in their businesses. In partnership with LWG, The Sak sources 100% of our leather from tanneries that comply with environmental sourcing processes and sustainable water usage. Many of our top styles are crafted with leather sourced from Gold Certified tanneries, the highest standard awarded.

Vachetta Leather

Vachetta is leather in its natural state. We use an environmentally friendly vegetable tanning process and minimal surface treatment, leaving the leather soft to the touch. Because the leather is unprocessed, natural variations will develop overtime, giving your bag a rich and unique patina.
