Men's wool jackets

Men's wool jackets sit at the point where tailoring meets outerwear, structured enough to look deliberate but casual enough to wear without a tie underneath.

Weight and weave

Cut in a tweed or heavier flannel wool, the fabric typically runs at 350-450g/m², heavier than a suit jacket but lighter than a full overcoat, giving genuine warmth without the bulk of winter outerwear. Tweed woven with an irregular surface texture catches light differently through the day, a detail sourced from mills that have supplied British tailoring for well over a century.

How men's wool jackets differ from a blazer

A wool jacket is generally cut with a more relaxed, less structured shoulder than a tailored blazer, closer in spirit to country outerwear, and often finished in a heavier tweed rather than the smoother worsted wool used for suiting. This distinction has remained consistent across Hackett London's outerwear since the brand's earliest collections, treating the wool jacket as a genuine layering piece rather than tailoring's casual cousin.

Can a wool jacket be worn instead of a blazer?

A wool jacket, particularly in tweed, works well as a more relaxed alternative to a blazer for smart-casual settings, though it reads less formal for business meetings requiring a sharper cut.

How should a tweed jacket be cleaned?

Dry cleaning is recommended, and ideally infrequently, since over-cleaning can flatten the natural texture that gives tweed its characteristic surface and warmth.

What's the difference between tweed and flannel wool?

Tweed has a rougher, more textured surface woven from thicker yarns, while flannel is brushed to a softer, smoother finish — both are heavier wools suited to colder weather.
