ONI Denim 669XX "Slubby XX Denim" 16.5oz Relax Spike Jeans



The XX denim is well known for its unique texture. If you are looking for a mid to heavyweight denim with a lot of character and a crazy slubby and neppy texture, this will be the best chance. The fabric is an ultra-low tension weave 16.5oz slub and nep indigo-dyed denim that produces snowy sprinkles of light-coloured highlights that arise gradually over its surface. To create this fabric, Oishi-San mixes different kinds of cotton and uses the iconic ONI low tension weaving technique to create a rugged and extremely uneven touch. It gets its name by old Levi´s jeans. For the first 17 years between 1873 to 1890, Levi’s waist overalls (as jeans were called then) were known simply as XX.

The jeans are made with all the superior-quality ONI details such as copper buttons, high-quality pocket bags, heavy-duty bar tacks and a custom veg-tanned deerskin leather patch with XX stamp.

The cut is the new mid-rise relax spike fit. The taper is aggressive so that it gives a slim-fitting silhouette while allowing for a lot of space at the thighs with a mid-rise. The inseam length is moderate, so this cut is perfect for those who don't like to wear double cuffs.

The legend of ONI is alive to this day. In recent years Oishi-San has devoted himself to experimenting with widely varying grammages, rough textures, different indigo dyeing techniques and novelty cuts while always maintaining a very limited production and wielding his experience in denim which now goes back more than 60 years.
