product description

Sashiko denim uses a traditional Japanese technique with running stitches that strengthen fabric and create detailed patterns. This method started as a way to make garments tougher and repair them, especially in rugged workwear denim. Today, Sashiko stands out for its unique look.

Our 12oz Sashiko denim combines style and strength. Despite its 12oz label, the thick weaving gives it the feel of a 15oz fabric. Made from 100% top-quality cotton looms, the 12oz Khaki Sashiko delivers both durability and style.

Johan is wearing size Medium. He is 180 cm tall.

We recommend tonal stitching for all our sashiko fabrics.

product care

Turn inside-out before washing. For denim and flannel, begin with a cold soak, then machine wash on a short cycle at 30°C (max 40°C / 100°F) with low or no spin. For waxed canvas, spot clean with cold water and a soft brush or cloth, never machine wash, dry clean, or use heat.

Hang or lay flat to dry. Do not tumble dry! Re-wax canvas as needed to maintain water resistance.

Shrinkage & Stretch
This garment is not industrially pre-washed, so some shrinkage is expected. Washed per the guidelines, the waist and inseam may shrink by 1″, with other areas adjusting proportionally.

Post-wash or soak, the waist will stretch back approximately 1″ with wear. High-stress areas also tend to return to pre-wash dimensions over time.
