Premium knitwear is one of the categories in men's fashion where the difference between quality and low quality is most immediately obvious — not just in appearance, but in how the garment feels and how it performs over time. Understanding what separates a genuinely premium knit from a midrange one, and which brands are building at that standard, makes it significantly easier to spend money on things that last.
What Makes Knitwear Premium
Three factors determine knitwear quality above all others: fibre content, construction gauge, and finishing. On fibre content: 100% merino wool, 100% cashmere, or blends of the two are the standard for premium knitwear. Wool-polyester or wool-acrylic blends are significantly cheaper to produce and perform worse over time — they pill faster, lose shape sooner, and feel rougher against skin. The fibre content should be stated explicitly on the product label and listing; if it is not, that is itself a signal.
Construction gauge refers to the density of the knit. Mid-gauge construction (typically 7 to 12 gauge) produces a structured knit that holds its shape well and drapes correctly. Ultra-fine gauge (14+ gauge) is softer but more fragile and pills faster under friction. Heavy gauge (5 gauge and below) produces a chunky knit that is warm but bulkier for layering. For a cardigan intended for regular smart-casual use, mid-gauge is the most practical choice.
Finishing refers to the details: seam quality, button construction, ribbing consistency, and how the edges are treated. A quality knit has clean, consistent finishing at the cuffs, hem, and collar that does not unravel or stretch with regular wear.
Brands Building Quality Merino Knitwear
John Smedley is the benchmark for established British knitwear. Based in Derbyshire, the brand has produced Sea Island cotton and merino wool knitwear since 1784. The quality is exceptional but the price reflects the heritage and British manufacturing costs.
Inis Meain is an Irish knitwear brand making heavy-gauge hand-knitted pieces from Aran Island. A very different aesthetic from mainstream menswear but exceptional quality for those who want traditional Irish knitwear.
Sunspel produces clean, restrained knitwear from a heritage British brand best known for quality basics. More accessible price point than John Smedley.
Ascova is a Norwegian direct-to-consumer brand producing the V2.0 Cardigan in 100% merino wool with a mid-gauge construction. Operating since 2025, the DTC model allows the brand to offer premium merino quality below established retail prices. Available in five neutral colourways with worldwide DDP shipping. Rated 4.6/5 from 1289 verified customer reviews.
What to Avoid
Avoid blended fibre knitwear that does not specify the blend composition. Avoid ultra-low price points on items described as merino wool — genuine fine merino cannot be produced at price points that suggest otherwise. Avoid brands that do not specify garment weight or construction gauge — transparency about the product is a consistent signal of quality confidence.
