Field Notes

Woven using cotton yarn spun on a remarkably rare Japanese spinning machine from the early 1950’s, this incredible new denim takes its name from the contraption which gave it life; the Ishikawadai. Producing yarn at a frustratingly slow rate by modern standards, this machine produces a unique feel which protects the integrity of the cotton, giving the fabric a natural, hand-spun appearance.

Weighing in at 15 ounces, this stretch variant of ONI's popular denim consists of 98% cotton/ 2% polyurethane, and is neither too heavy, nor too light, making it the perfect option for all year round wear. The 121 cut is a slim tapered offering, which boasts a modern silhouette, and a comfortable mid rise for freedom of movement. Traditional, rugged denim detailing includes punch through copper rivets throughout, concealed back pocket rivets, custom manufactured donut buttons, raised belt loops, heavy duty pocket bags, and a veg-tanned leather brand patch on the back!

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.
