Wool Suits
Men's wool suits
Men's wool suits remain the default choice for good reason: no other fibre balances structure, breathability and longevity as reliably across a full working year.
Wool weight and weave
Hackett London's wool suits run at roughly 260-280g/m² in a plain worsted weave for year-round wear, with heavier flannel options for winter and a lighter tropical wool for summer. The wool content is never diluted with polyester in the outer shell, which is precisely why the fabric holds its shape and drape over years of wear rather than losing structure the way a wool-poly blend eventually does. A half-canvas construction in the jacket chest allows the lapel to roll naturally and the fabric to move with the body.
Why men's wool suits outlast other fabrics
A wool suit built with a floating canvas construction will outlast a fused-construction alternative by a decade or more under normal wear, since the canvas moves independently of the outer cloth instead of being bonded to it and eventually bubbling. Wool itself resists creasing far better than cotton or linen, recovering its shape overnight on a proper hanger rather than needing constant pressing.

Choosing the right wool weight for the season
A tropical wool, woven with more open space between fibres, suits warmer months and long days spent moving between meetings, while a heavier flannel wool holds up better through a cold winter. A mid-weight worsted wool around 260-280g/m² works as a genuine year-round compromise for anyone who only wants to own one suit.
What's the best wool weight for a year-round suit?
A mid-weight worsted wool, typically 260-280g/m², balances warmth and breathability well enough to wear comfortably across most of the year without needing a seasonal swap.
Do wool suits need dry cleaning after every wear?
No, over-cleaning breaks down wool fibres faster than regular wear does; airing the suit on a broad-shouldered hanger between wears and dry cleaning only occasionally is generally better for the fabric's longevity.
Is 100% wool better than a wool-blend suit?
A pure wool suit typically holds its shape and drape better over time than a wool-polyester blend, which tends to lose structure and develop a slight sheen with age.
