Blazers
Men's blazers
Men's blazers from Hackett London bring together British sartorial heritage and precise construction: clean structure, carefully selected fabrics and an ease of wear that carries from the boardroom to the weekend without effort.
Construction and fabric quality
A well-made men's blazer reveals its quality from the inside out. Hackett London, founded in 1983 with direct ties to the Savile Row tradition, builds its higher-tier models with a floating canvas chest piece: an internal structure that is not glued to the outer fabric but allowed to move with it, adapting to the wearer's body over time. The result is a blazer that holds its shape without rigidity and improves with wear. Pure wool models — 100% merino in the more formal cuts, at weights between 280 and 320 g/m² — offer a natural drape and thermal regulation that synthetic blends cannot replicate. Cotton and linen options are designed for transitional seasons, at weights between 200 and 240 g/m², providing structure without weight.
The men's blazers in the Hackett London collection range from a defined slim fit with a marked waist to a natural-shoulder regular fit built for ease of movement. Pick stitching on the lapels — hand-finished in the sartorial models — is one of the construction details that separates a considered blazer from a generic one.
Fabric palette and seasonal range
Hackett London works a colour palette that holds together tradition and the contemporary wardrobe. Navy, slate grey, camel and tobacco brown sit alongside Prince of Wales checks and thin chalk stripes. Men's blazers in Scottish-origin tweed — handwoven using techniques that guarantee geographic provenance — carry a surface that catches the light differently at every hour. Flannel models, with their brushed wool hand, offer warmth and a softness that works particularly well through the colder months. Internal linings in silk or high-density viscosa, with clean-finish internal pockets and surgete-stitched seams, are the details that are felt rather than seen.
How to wear a Hackett men's blazer
The men's blazer collection is built for a wardrobe that shifts register more than once a day. Two concrete combinations:
Grey wool blazer over a pale blue Oxford shirt, heavy cotton chinos and brown leather derbies: the working week uniform that requires no explanation and holds through a full day.
The same blazer over a merino crew-neck in navy, flannel trousers and suede loafers: the register drops, the structure stays, the look carries from late afternoon onward.
Models with natural shoulders and a semicanvas build are particularly well suited to open-collar wear: the lapel holds its line without a tie to anchor it.
How to find your size in Hackett blazers
Hackett London men's blazers follow standard European sizing with a few specifics worth knowing. Pure wool models tend to adapt to the wearer over the first weeks of use: if between two sizes, the smaller is usually correct for the slim fit. Technical and cotton-blend models have more inherent stretch and fit more immediately. Sleeve length is calibrated for a height between 178 and 182 cm; outside that range, the regular fit allows more margin for tailoring adjustments.
What fabrics are used in Hackett London men's blazers?
Hackett London sources merino wool from high-altitude New Zealand farms, high-density combed cotton and Harris Tweed carrying the certified Scottish-origin Orb mark. Top-tier models may incorporate cashmere or Como silk in the internal lining. Exact composition is listed on each product page.
How should a men's blazer fit?
The shoulder seam should sit exactly at the edge of the natural shoulder — not dropping onto the upper arm, not pulling toward the neck. The chest should close without tension when buttoned; the back should hang smoothly without horizontal creases across the shoulder blades. The sleeve should show approximately 1–1.5 cm of shirt cuff when the arm is relaxed. These three points cover the majority of fit issues in any blazer.
What is the difference between slim fit and regular fit in Hackett blazers?
The slim fit has a narrower chest, a defined waist suppression and tapered sleeves; it works best on proportionate builds with defined shoulders. The regular fit has wider natural shoulders, more room through the chest and a straighter hang from the torso — the correct choice for those who prefer ease of movement or layer underneath. Both share the same materials and the same construction standard.
How do you care for a wool blazer?
Wool blazers from Hackett London require dry cleaning as the primary method. Between uses, hanging the blazer on a wide-shoulder hanger for at least an hour allows the wool to recover its shape naturally. Avoid the washing machine on any model with internal canvas: heat can cause the outer fabric and lining to shrink at different rates, permanently distorting the structure. For surface marks, a clean damp cloth applied cold without rubbing is the correct first response.
