evidence: The best options, in my opinion, are real sustainable leather that is surplus (leftover from agriculture) or vintage or vegan leather that is biodegradable (i.e. NOT PU, PVC, or ‘pleather’). You can also look for new-age leathers that are grown in a lab or made from pineapple or orange fibers but these are scarce on the market right now. More on this in my leather post. An ethical note: SixChel’s pants are vegan leather sourced from Italy. While this is not the most sustainable option, it is ‘cruelty-free.’ However, if the environment is your main priority, I suggest looking at SixChel’s other pieces that are made from eco-friendly Tencel and hemp. I stand by my endorsement of these pants because this is the designer’s first collection and she has shown a strong commitment to continuous learning and improvement when it comes to her supply chain and materials.

Currently, she uses Tencel, hemp, organic cotton and vegan leather in her line and continues to incorporate more sustainable practices as she grows.
