A good cashmere sweater is one of the few genuinely transformative buys in a wardrobe: warmer than wool at a fraction of the weight, soft against bare skin and quietly smart in a way no synthetic can fake. It is also one of the easiest places to overspend or to be disappointed, because the gap between cashmere that pills within a month and cashmere that lasts a decade is not always visible on the hanger. Below are six cashmere sweaters worth the investment at every level, from accessible high-street knits to a Scottish-milled splurge, with honest guidance on where your money goes.
What to look for
Not all cashmere is equal, and a handful of signals separate the good from the regrettable. Ply refers to the number of yarns twisted together, so a two-ply knit is generally more durable and less prone to holes than a single-ply one of the same gauge. Fibre length matters too: longer fibres shed and pill less, which is why heritage mills make so much of using the longest fibres. Give the knit the squeeze test where you can, as a dense, springy fabric that recovers its shape is a better sign than a thin, papery one that stays stretched. A little initial pilling is normal even on excellent cashmere; persistent, heavy pilling is not. Care is the final piece of the puzzle, and it is worth reading our rules for washing cashmere before you buy, because gentle hand-washing and flat drying extend the life of any jumper far more than the price tag does. Styled well, a cashmere jumper layers over a white shirt or under a wool coat, and it is just as much a cornerstone of a man’s wardrobe, as our guide to men’s wardrobe staples sets out.
It is also worth being realistic about what your budget buys. Affordable cashmere from the high street is usually a lighter, often single-ply knit: genuinely lovely to wear, but thinner and shorter-lived than the dense two-ply pieces heritage mills produce. Neither is wrong, they are simply different purchases. An £50 jumper you wear gently for a few seasons can be excellent value; a £270 one you keep and mend for a decade can work out cheaper per wear. Think too about neckline and fit, as a crew neck is the most versatile layering shape, a roll-neck adds warmth and polish, and a relaxed fit reads more modern than a slim one. With those distinctions clear, here are the six we would spend on.
1. Marks & Spencer Autograph Pure Cashmere Jumper
The most useful thing about M&S’s Autograph cashmere is simply how accessible it is: genuine pure cashmere, on the high street, with easy in-store returns if the fit is wrong. The round and crew-neck styles are deliberately classic, and the colour range covers the neutrals most people actually reach for. It leads the six as the sensible entry point, the jumper that proves you do not have to spend three figures for real cashmere. Treat it kindly and it rewards you. At a budget price of around £49, it is remarkable value for the fibre. The Sixated take: the easiest first cashmere jumper to recommend, especially if you want to try the fabric before committing more.
2. Quince Mongolian Cashmere Crewneck
Quince built its reputation on a single promise: real cashmere at a price that undercuts almost everyone. By selling direct and keeping the range tight, it offers a plain crewneck for less than many high-street blends. It makes the six as the value champion, the jumper to buy if price is the main barrier between you and cashmere. We will be candid, though: it ships to the UK, but you should factor delivery times and any import costs into that tempting headline figure. At a budget price of around £55, it is still keenly priced. The Sixated take: excellent value as an everyday cashmere jumper, provided you go in clear-eyed about the import logistics.
3. Uniqlo Cashmere Crew Neck Jumper
Uniqlo’s cashmere has become a seasonal ritual for a reason: it is consistent, widely stocked and offered in a genuinely broad palette, so matching last year’s jumper or buying a second colour is rarely a problem. The pure-cashmere construction feels soft and holds up well with sensible care, and the fit is a clean, traditional crew. It earns its place as the dependable mid-range default, the low-drama choice when you just want a good cashmere jumper without research. The breadth of colours is a genuine advantage too, because it lets you build a small capsule in complementary shades over a couple of seasons rather than hunting for an exact match later. At a mid-range price of around £80, it is fair and predictable value. The Sixated take: not the most special knit here, but the most reliably available, and a wardrobe mainstay.
4. John Lewis & Partners Cashmere Crew Neck Jumper
John Lewis’s own-label cashmere occupies the comfortable middle ground of everyday luxury: a touch more considered than the cheapest options, with the reassurance of the retailer’s customer service and returns behind it. The cuts and colours are classic by design, aimed at lasting several seasons rather than chasing a trend. It makes the six as the safe, grown-up choice, particularly if you value buying in person and the backup if something goes wrong. At a mid-range price of around £99, it sits just below the psychological three-figure line for a reason. The Sixated take: the pick for anyone who wants quality and good service without stepping up to designer pricing.
5. COS Pure Cashmere Jumper
For cashmere with a modern attitude, COS is the obvious call. Its pure-cashmere jumpers lean relaxed and architectural, with the slightly oversized, minimalist silhouette the brand is known for. This is the jumper for anyone who finds a traditional crew too safe and wants their knitwear to feel current. It earns its spot as the style-led option, the one that updates the fabric’s classic image. The trade-off is that the generous cut will not suit everyone, so consider sizing down for a neater line. At a mid-range price of around £135, it is the priciest of the mid-tier. The Sixated take: buy it for the shape as much as the fibre, and size thoughtfully.
6. Brora Scottish Cashmere Jumper
At the summit sits Brora, knitting its cashmere in a Scottish mill from long-staple fibres since 1993. This is the investment jumper in the truest sense: dense, soft and offered in the painterly colours that have become the label’s calling card, built to be worn, loved and mended across years. It closes the six as the buy-it-for-life option, the one purchase here that should outlast the rest. Yes, it costs several times the high-street picks, and that is the point. At a splurge price of around £270, it asks for commitment and repays it. The Sixated take: if you are going to own one serious cashmere jumper, this is the one we would save for.
One last point that applies to every jumper here: care does more for longevity than price. Fold cashmere rather than hanging it, give it a day’s rest between wears so the fibres recover, de-bobble gently with a comb or cashmere stone, and hand-wash or use a dedicated wool cycle with cool water. Store it clean over summer with cedar or lavender to deter moths, which are the single biggest threat to a good cashmere jumper. Do this and even the cheapest knit on this list will outlast its price tag.
Six cashmere sweaters, from a £49 high-street surprise to a Scottish heirloom. For most people the smart strategy is a pair of affordable everyday jumpers plus one investment piece you truly love; combine that with careful washing and even the cheapest knit here will serve you far longer than its price suggests.
