Field Notes

ONI’s masterful 20oz ‘Secret Denim’ is back, but this time in double black. This iconic slubby denim is renowned the world over for its super loose weave, and characteristic slubby texture, boasting a heavyweight feel which moulds to the shape of your body over time. Durable details have been retained, including punch through copper rivets, a deer skin leather patch, heavy duty cotton pocket bags, and concealed back pocket rivets, to ensure that your jeans live up to the highest standards.

This regular straight offering gives a mid century silhouette, and features a button fly, and comfortable mid rise, making it a very versatile jean for any time of year. Never ones to overlook the finer details, the brand have included a bold red selvedge line on this specially woven denim, for a touch of interest in your turn-ups.

    How to Wash
    Step 1

    When you’re ready to wash your jeans, button the fly and turn them inside out. Doing up the fly ensures the jeans maintain their shape, and turning them inside out avoids unwanted marks from the washing machine drum on the indigo.

    Step 2

    Place the jeans in your washing machine with neutral detergent, and set them on a non/low-spin wash at cold–20 degrees for raw, or up to 30 degrees for pre-washed. High spin may cause unwanted 'lightning fades', and washing too hot can cause excess shrinkage, so it’s important to follow these steps carefully!

    Step 3

    Once your jeans are done washing, hang them somewhere safe and allow them to air dry. Putting your jeans in a tumble dryer has a high chance of degrading the fabric and misshaping your jeans. Make sure wherever you hang them has proper drainage, as you’ll be expecting some indigo runoff.
