Gray ‘POSZ-53’ Trousers UNITRA
Part of the POSZETKA x UNITRA limited collection, inspired by “The Beauty of Polish Engineering” — the motto behind the revival of the Polish hi-fi legend.
The trouser side of our collaboration is a new version of our proven POSZ-53 cut with military and workwear roots, now equipped with a practical utility pocket — originally designed to hold tools and, these days, more likely a smartphone (we tested it).
In our search for the right fabric, we found a common thread: Japan is home to both some of the best audio components and some of the best cotton fabrics — and that’s where this HBT fabric came from. Its texture is inspired by denim: gray and undyed yarns are woven into a fine herringbone pattern, creating a beautiful matte surface that echoes the brushed aluminum UNITRA often uses in its designs. Since both brands believe in the strength of the Made in Poland label, the trousers — like the rest of the POSZETKA x UNITRA collection — are cut and sewn in Poland.
We particularly like wearing them on their own — with blazers, other overshirts, or simply a shirt or T-shirt for a more relaxed look — while the UNITRA team remains a fan of the “uniform” pairing with the chore coat.
