Black Sign

Saya Adjustable Waist Trousers - Black Cotton/Linen


Free USA Shipping on orders over $300


Not quite a work pant, not quite an easy pant, the Saya Trousers land somewhere right between both. The fit is excellent, with a high rise and relaxed top block that features an internal drawstring at the waist, allowing you to covertly secure a perfect fit every time you wear them. The legs are wide and straight, and will fit (and look good) over just about any shoes or boots I can think of.

The fabric is a custom chambray, developed for Black Sign and composed of 65% cotton & 35% linen yarns. It's sturdy, with a softer-than-average hand for a chambray and a more fluid drape (as would be expected of a linen fabric). Also, as is characteristic of both linen and chambray, the fabric breathes well in hot weather.

The surface of the fabric features a modified Saya pattern done in dot form. This pattern originated during and has been passed down since the Japanese Edo period (1603 - 1868), and represents a wish for "uninterrupted longevity and prosperity". This pattern is very subtle, and only becomes fully apparent up close - visually reading as solidly black from afar.

In addition to the internal drawstring, these also feature belt loops, so you can dress them up further whenever desired. Beyond that, details are very minimal, with two front slash pockets and a single rear bucket pocket for storage, & felled leg seams for durability.

These fit true to size, and feature an internal drawstring that can be used to secure the waist to the ideal fit every time. Minimal shrinkage with cold wash and hang dry.
