First and foremost, we would like to establish that we identify our brand as an ‘ethical’ rather than a ‘sustainable’ one. Unlike many great initiatives, we don’t utilize recycled fabrics, vegan materials, etc. Despite our admiration for such initiatives, we believe that our ‘sustainability’ is in the quality of our product and how we do business.

We adore old craftsmanship and heritage; it’s what we have based our brand around. In adherence to this, we produce our products meticulously with second-to-none materials that have been ethically sourced, and, we only work with manufacturers we trust and personally know. We know there is always room for improvement, and we will always strive to improve our production chain. Just know that you can enjoy your Sine & Cosine products care-free and always will.
