Men's blazers
Men's blazers from Hackett London earn their place in every wardrobe that takes dressing seriously: precise construction, cloths sourced from the best British and Italian mills, and a silhouette that works without trying from a Tuesday morning in the City to a Saturday afternoon in Chelsea.
Cut and construction of men's blazers
Hackett London has built its men's blazers around a clear conviction since 1983: structure should serve the wearer, not constrain him. The higher-range models use a floating canvas construction — a chest piece that is hand-stitched to the outer cloth rather than fused, allowing the fabric to move naturally across the chest and settle into the body with wear. The result is a blazer that holds its shape through a full working week without the stiffness of an interlined chest. Lapels in the collection range from the classic notch, which suits every occasion from boardroom to racecourse, to the more declarative peak lapel on the double-breasted cuts.
Two primary fits run through the range. The slim fit carries a defined waist suppression and a clean chest line suited to a proportionate frame; the regular fit builds in natural-shoulder construction and additional room through the chest, which is the correct choice for layering or for those who prefer ease of movement without sacrificing a considered silhouette. Both share the same standard of internal finishing: full lining in silk or high-density viscose, interior ticket pocket, and sleeve buttons that actually unbutton on the tailored-tier models.
Fabrics and seasonal cloths
The men's blazers Hackett offers this season span a range of cloths that moves between the classical and the contemporary without losing its footing in either. Core models arrive in 100% pure wool — predominantly a mid-weight 260–280g flannel or a smooth worsted — which offers the right balance of drape, warmth and resilience across the London working year. The seasonal range introduces mid-weight tweed with its characteristic irregular surface, double-twisted merino wool in navy and charcoal, and cotton-linen blends for the warmer months that breathe without losing the structured front that separates a blazer from a casual jacket. The palette remains anchored in Hackett's house territory: ink navy, mid-grey, camel, and a deep burgundy that has been in heavy rotation every autumn since the brand's early Jermyn Street days.
Internal finishing carries its own authority. The full lining falls cleanly and helps the jacket slide on and off with ease; the chest pocket silk square keeper — present on the more formal models — is a small detail that reveals the level of thought behind the pattern.
How to wear men's blazers from Hackett London
The strength of men's blazers from Hackett lies precisely in the range of registers they cover without announcing any effort. Two concrete combinations that illustrate the point:
Navy wool blazer over a white poplin shirt, mid-grey flannel trousers and Oxford brogues in tan leather: the kind of quiet that reads correctly at Ascot, at a Pall Mall lunch, or at a client meeting that runs into early evening.
The same blazer worn open over a merino crew-neck in oatmeal, dark indigo chinos and suede loafers: the formality drops, the presence holds, and the cloth earns its place across a Saturday that starts at a gallery and ends at dinner.
Worn either way, the slim fit men's blazer in the Hackett tailored tier benefits from the floating canvas chest, which means the front drapes flat when the jacket is open — one of those construction details that separates a considered garment from a merely decent one.
How to choose your size in Hackett men's blazers
Men's blazers Hackett London offers follow standard European chest sizing, with some useful nuances to bear in mind. Pure wool models have a degree of natural body in the cloth that softens with wear; if you sit between two sizes, the smaller will give the cleaner line in the slim fit. Models in cotton-linen blends carry more immediate ease and tend to run true to size. Standard sleeve length is calibrated for a height between 178 and 182 cm; above that, the regular fit accommodates alterations more cleanly due to its additional seam allowance at the sleeve head. The chest seam is the correct point of reference when fitting: it should sit at the natural shoulder break, no further.
What is the difference between slim fit and regular fit in Hackett men's blazers?
The slim fit suppresses the waist more noticeably, carries a closer chest and narrower sleeves, and is designed for a proportionate frame where the shoulder is well defined. The regular fit uses a natural-shoulder construction with a straighter cut through the body, more chest room and a longer back vent that allows easier movement; it is the right choice for layering a knitwear piece underneath or for those who prefer the slightly more relaxed silhouette associated with classic British tailoring. Both fits are built to the same construction standard and use the same mill cloths — only the pattern block differs.
Do Hackett men's blazers use full canvas construction?
The tailored-tier models in the Hackett London blazer range use a floating canvas chest piece, hand-stitched to the outer cloth and left free from the lining. This allows the fabric to mould to the chest over time rather than remaining rigid. Entry-level models may use a fused or half-canvas construction, which is lighter in weight and requires less maintenance; the construction method is noted in the product specification of each style. Both approaches produce a well-structured front, but the floating canvas delivers a more organic drape with wear.
How should I care for a wool blazer from Hackett?
Dry cleaning is the primary care method for Hackett wool blazers. Between wears, hanging the jacket on a wide, shaped wooden hanger for at least an hour allows the wool fibres to recover their natural form — wool breathes and releases creasing without heat if given sufficient time and air. Machine washing is not suitable for any blazer with canvas construction or a structured chest piece, as water shrinks the outer cloth and the interlining at different rates, permanently distorting the front. For minor surface marks, a soft brush along the grain of the cloth is usually sufficient.
Can Hackett men's blazers be worn without a tie?
Without question. The majority of men's blazers in the Hackett London range are cut with an open collar in mind: the lapel width and roll are proportioned to sit cleanly whether the shirt is buttoned to the top or left open. The navy wool blazer in particular — the most versatile piece in the collection — works as well with a collarless shirt and no tie as it does with a formal spread collar and a silk knitted tie. The right kind of quiet, in both cases.
