How do we quantify what that one word means?
To start with, we can look on a macro level and highlight the fact we use recycled fabrics and trimmings, like binding, webbing and straps. We can also look at how these are all from reputable and traceable mills, ones that I have a personal relationship with from my years working in the industry. 
‘The garment industry is producing twice as many clothes , as it was in the early 2000’s, but the amount of times worn has decreased significantly’

We can confirm that the fabrics we use have been specifically selected because of the way they have been produced, fully accredited to several certified environmental standards, we are proud to be experts in this field already, and to have done our due diligence in this area.
Or we can zoom out a little and talk about our manufacturing partners, all reputable, we have visited them all and they all pay their workers a fair living wage.
However, it is no longer enough to focus on these claims alone to make the product sustainable.
Another factor that influences a products ‘sustainable’ credentials is built to last, so consumers need to buy less. By buying the best we can afford, and as a brand, making sure these products are durable, ensures our customers will love and cherish them and use them for many adventures. This adds, in our eyes, to the sustainable considerations.
However, these two points do not end the story of sustainability. 
‘Today, less than 1% of clothes produced are recycled’

The truth is there is a scary amount of products being produced in the world today, and when starting a clothing brand, it was a question I seriously grappled with :
Does the world need any more stuff?
Picture the scene, if you will. Season after season, brands produce vast quantities of stock, for it to sit in a warehouse.
The hope is it will all sell and if it doesn’t it’s either discounted, sold on to retailers, or shipped off where it can become someone else's problem and then, either de-labeled and sold off, burnt or sent to landfill.
This is something that I, as a founder, did not want to contribute too.
So I decided Petrichor Projects would do things differently.
We only produce what we can sell.
To me, that is a truly forward thinking and sustainable choice.
