Product Insights
The Djab Mechanic Patch Shirt reimagines Japanese amekaji workwear with a fashion-forward, sustainable approach: an open pyjama collar, vintage chest patch, and back graphic replace a pointed collar and stiff materials, while a lyocell-rich sateen (32% REFIBRA TENCEL lyocell from closed-loop processing, 50% reprocessed cotton) delivers breathability, moisture-wicking, a cool feel, and a soft drape that resists post-wash stiffness and keeps the oversized fit off the body for airflow. Priced at 89 CAD (sale 69.95)—undercutting heavy-duty brands like Iron Heart (starting ~350 CAD) and offering a more fashion-forward alternative to Carhartt WIP—the tradeoff is that this softer blend is intended for casual lifestyle wear rather than heavy work.
Verified claims
- Design
- The vintage chest patch and back graphic print replicate the look of hand-customized Japanese amekaji workwear.
- Value
- 89 CAD (sale 69.95) undercuts brands like Iron Heart (starting ~350 CAD) while offering a more fashion-forward design than Carhartt WIP.
- Material
- 50% reprocessed cotton, 32% REFIBRA TENCEL lyocell, 18% cotton; lyocell made via a closed-loop process recovering 99%+ of solvents.
- Breathability
- Breathable, moisture-wicking sateen that feels cool and stays soft after washing.
- Fit and airflow
- The fluid drape of the Lyocell-rich sateen prevents the oversized boxy fit from ballooning; it falls cleanly off the shoulders and pools softly at the side splits.
- Care
- Machine wash cold on gentle cycle; tumble dry low to protect patch and texture.
- Post-wash feel
- Lyocell in the blend resists post-wash stiffness and keeps fabric surface refined.
- Intended use
- Softer blend is suited for casual lifestyle wear, not heavy-duty work.
- Collar style
- Open pyjama collar replaces pointed collar for a casual, lounge-inspired look.
- Drape
- Lyocell-rich sateen gives a soft drape, unlike stiff workwear materials.
- Sustainability
- The REFIBRA™ TENCEL™ Lyocell is made from recycled cotton scraps and sustainably sourced wood using a closed-loop process that recovers over 99% of solvents.
- Warm-weather suitability
- The sateen fabric is a medium-weight weave that is breathable and moisture-wicking, making it suitable for warm-weather wear.
