Men's casual blazer

The men's casual blazer from Hackett London shares its DNA with the brand's sartorial models but pursues a different goal: to structure a look without stiffening it, to add presence without adding ceremony.

What makes a blazer casual

The distinction between a formal and a men's casual blazer is constructional before it is aesthetic. Hackett London separates its casual models through four main characteristics: a semicanvas or uncanvassed build — which lightens the internal structure without eliminating it entirely — natural shoulders with no rigid padding, a medium-width notch lapel, and natural horn or mother-of-pearl buttons rather than the fabric-covered buttons of formal tailoring. The result is a jacket that wears lightly, that does not need a shirt and tie to work and that adapts to a wide range of daily situations without demanding thought.

The fabrics in the Hackett London men's casual blazer range reflect this orientation: high-density combed cotton, cotton-linen blends, merino wool at lighter weights between 200 and 260 g/m², and technical wool-nylon mixes that hold up better to sustained daily activity. Hackett London's longstanding involvement in British polo and equestrian events at Ascot produced garments built for extended physical wear — a quality that transferred directly into the brand's urban casual range.

How to wear a casual blazer

The Hackett London men's casual blazer is built exactly for the wardrobe that shifts register more than once during the week — from office to lunch to evening, often without the opportunity to change. Two concrete combinations:

Navy cotton casual blazer over a white cotton jersey polo, khaki chinos and white leather trainers: the Saturday morning in the city look that maintains a composed presence without overstating the effort.
The same blazer over a pale blue Oxford shirt worn open, dark indigo jeans and brown leather loafers: the direct transition from office to evening drinks, with no change required.

Hackett London combed cotton models in navy, bottle green and grey are the most versatile in the casual range: they work with almost everything and require the same care as a good quality shirt.

The casual blazer and smart casual dress codes

In most international professional environments today, a quality men's casual blazer covers the full range of smart casual contexts — from creative meetings to informal business dinners. Hackett London's offer in technical cotton or lightweight wool sits exactly in this space: more structured than a cardigan, less demanding than a formal wool blazer, considered enough to communicate care without the appearance of effort.

How to find your size

Hackett London men's casual blazers in cotton and blended fabrics have more inherent stretch than sartorial wool models: fit is more immediate from the first try and leaves more margin on size choice. Slim fit casual models still carry a more defined waist suppression than the casual standard of most brands: those who prefer ease of movement will find the regular fit more practical for daily use without compromising the overall look.

Can a casual blazer replace a formal jacket at the office?

It depends on the workplace dress code. In environments with a business casual standard — the majority of offices in creative, technology and service sectors — a Hackett London casual blazer in cotton or lightweight wool is fully adequate. In business formal environments — banking, law, senior consulting — the casual blazer works on non-meeting days, but having a sartorial wool blazer available for representation occasions remains the more considered approach.

Can a cotton casual blazer be machine washed?

Hackett London cotton casual blazers without internal canvas generally tolerate a delicate machine wash at 30°C where the care label confirms this. Use a laundry bag and a gentle cycle. Avoid high-speed spin: heavy cotton distorts at the seams under sustained centrifugal force. Iron while still slightly damp, on the reverse, at a medium heat setting; the shoulders require a tailor's ham or a padded surface to hold their shape while pressing.

What is the difference between a casual blazer and a sports jacket?

A casual blazer maintains a basic tailored architecture — shoulders, lapels, buttons — even if simplified in its internal construction. A sports jacket may incorporate zips, bellows pockets, a hood, waterproof technical materials. A Hackett London casual blazer is always recognisable as a tailored jacket in its overall form; its casualness lives in the materials and internal build, not in the external silhouette.
