SAMURAI JEANS SIN25-02W Western Cut Cheese Indigo Heavy Flannel Work Shirt

About this product

The Samurai Jeans SIN25-02W Western Cut Work Shirt showcases the brand’s unmistakable approach to heritage fabrics and rugged construction, blending traditional indigo dyeing techniques with heavyweight flannel comfort to create a piece built for years of hard wear and beautiful aging.

Cut from Samurai’s original 'Cheese Indigo' heavy flannel, the fabric features a dense 2/2 twill weave that delivers real substance, warmth, and structure. Thick indigo cheese-dyed yarns are paired with specially reactive-dyed colored yarns to form a rich check pattern with deep tonal contrast. Unlike conventional rope-dyed indigo, the cheese dyeing method saturates the yarn core, resulting in slower, more gradual fading that retains its character while developing a subtle, lived-in patina over time.

The texture is weighty and tactile yet soft against the skin – the kind of flannel that feels closer to a light jacket than a shirt, making it ideal for layering through colder seasons.

Construction is unapologetically workwear-driven. Triple-stitched rolled seams reinforce stress points for long-term durability, while triple chain-stitched run-off side seams add both strength and authentic vintage character. Double-fabric forearm reinforcements provide extra resistance where wear naturally occurs, and cotton lining at the cuffs, collar, and placket improves both comfort and longevity.

Details like indigo-dyed nut buttons, symmetrical Western-style chest pockets and the iconic Samurai Union Ticket complete the design. The Western cut silhouette keeps the profile clean and balanced, offering a timeless fit that works equally well layered over a tee or under a jacket.

Fit Notes: Although this is a Japanese-made shirt, we carry the Western-cut version of Samurai flannels, which fits closer to standard Western sizing. If you typically wear a size M in American shirts, a size M should fit well here. As always, we recommend consulting our size chart to ensure the best possible fit.
