This jacket uses 14.0oz original selvedge sashiko fabric woven on a power loom . The surface of the fabric uses the most concentrated indigo yarn dyed using hank dyeing for both the warp and weft, achieving a deep color. To faithfully reproduce the uneven texture and thick feel unique to sashiko , the weaving density has been increased to the extreme. It has been reborn as a new design that blends with American work style and harmonizes with modern lifestyles . Based on the style of a 2nd type denim jacket, it has been made more comfortable to wear with a more relaxed fit from the chest to the armpits, and additional pockets have been added under both arms to make it a more functional jacket.
