The Onyx 5" Gentleman's Chino is the blacked-out athletic cut in the Gentleman Chino lineup. It is made for customers who want the shortest, most mobile fit with the clean versatility of a dark technical chino short.
Onyx gives the piece a sharp, minimal look that works with almost anything: white tees, black layers, grey hoodies, technical jackets, and graphic tops. The 5" inseam creates a confident above-the-knee profile built for warm weather, movement, and a more active uniform.
Breathable performance fabric keeps the short comfortable through daily wear, while reinforced belt loops provide a stronger waistband feel. Zippered rear pockets add secure storage without disrupting the clean silhouette. The Onyx 5" Gentleman’s Chino is the go-to option when you want a technical chino short that feels fast, minimal, and easy to wear on repeat.
