Siena Cav Twill Black Trousers

$129 $179

Sizing Information

The Siena is cut with a tailored rise and a streamlined leg that falls cleanly from the hip. Front pleats provide additional room through the seat and thigh, while side adjusters allow the waist to be refined without adding the bulk of a belt. Cuffed hems lend weight and definition to the finish.

Fabric & Care

Woven from premium wool with added elastane, the cavalry twill cloth combines natural breathability and resilience with comfortable flexibility. Its distinctive diagonal structure supports a smooth tailored drape, helping the trousers retain their shape through extended wear.

Fabric: Premium Wool with Elastane

Product Description

A sharper take on tailored men’s pants, the Siena Cav Twill Black Trousers are woven from premium wool with a touch of elastane for structure, flexibility and a clean drape. The cavalry twill weave introduces a subtle diagonal texture to the black cloth, giving the fabric greater depth than a conventional flat finish.

Front pleats provide ease through the upper leg, while adjustable side tabs maintain a streamlined waistband without the need for a belt. Finished with a tailored profile and cuffed hems, they offer a polished foundation for business, formal occasions and elevated evening dressing.

Fractional Fitting

Our range of tailoring comes in three sleeve/jacket lengths to ensure the perfect fit.

Half-Canvas Construction

Light and minimalist, our half-canvas construction ensures a better fit and drape.

Australian Merino Wool

Premium Wool

Stylist Notes

For a refined monochromatic look, pair them with a black or charcoal knit polo beneath a textured sports jacket. A crisp white shirt and black leather shoes create a more formal combination, while a pale blue shirt and navy jacket introduce understated contrast for the office.

The clean black tone also works well with ivory, taupe and soft grey layers. Keep accessories minimal to allow the pleated construction and cavalry twill texture to define the look.
