What is Compostable Fashion?

By definition, every material is biodegradable. However, this process can take hundreds if not thousands of years. Synthetic products often leave behind hazardous toxins and microplastics that bleed into the ocean and corrupt our coral reefs.

Meanwhile, compostable products are broken down in organic matter much more quickly, but only with the help of human intervention. For something to be compostable, it must be made entirely of non-toxic materials so that no microplastics or toxins are left behind.  

Our compostable garments are created to last just as long as you'd like to wear it. After that, it can be composted (no worry, we handle this) to create healthy, organic matter, free from synthetic or hazardous materials. Inspired by nature, our blazer is perfectly evolved for you to enjoy, made from unbleached, undyed linen that is OEKO-TEX® certified.

A New Life Blazer

It's cut from a simpler cloth.


Flax fibers are known for creating soft, breathable, circular fabrics.


Organic cotton is a regenerative resource made without the use of toxic chemicals.

This is Farm-to-Fashion (and then back to farm again) at its finest, without compromising on a tight-knit supply chain.


Why Join Us?
