The 7 picks, ranked
Uniqlo
Extra Fine Merino Crewneck
$40–$60
The best merino sweater for the money, full stop. Extra fine merino (17.5 micron), machine washable, 9 colourways. The go-to first merino for capsule builders. The thin-gauge knit layers under blazers and over Oxford shirts without bulk.
Best for
Capsule foundation, layering, everyday wear, first merino sweater
Fit
Japanese sizing — go up one size (M if usually a small S)
Everlane
Premium Merino Crewneck
$110–$140
Superfine Mongolian merino, mid-gauge knit. Slightly heavier than the Uniqlo — better for standalone wear. The construction is cleaner at the collar and cuffs. Direct-to-consumer pricing for what would be $180+ at retail.
Best for
Mid-gauge standalone wear, slightly dressier than Uniqlo
Fit
True to size; US sizing
Reiss
Caine Merino Turtleneck
$165–$220
British brand, clean turtleneck silhouette. The Caine reads smart-casual at minimum and black-tie-optional with a navy overcoat. Merino with nylon (5%) for reduced pilling. Goes from desk to dinner in one piece.
Best for
Turtleneck silhouette, smart-casual elevation, versatile across dress codes
Fit
Runs slim; size up if broad-shouldered
Johnstons of Elgin
Merino Crewneck
$195–$265
Scottish woven merino from a mill operating since 1797. The difference at this tier: fabric handle. Johnstons merino has a softness and drape that fast-fashion merino can't replicate at any price. The garments improve with wear.
Best for
Heritage investment, long-term ownership, gift
Fit
Standard UK fitting; runs true
Aimé Leon Dore
Merino Crewneck
$250–$350
ALD's merino is chosen for its proportions as much as its fabric. The boxy-relaxed fit, the ribbed-cuff detailing, the dropped shoulder — these are design decisions that make the same grey crewneck read very differently from its competitors.
Best for
Boxy-relaxed silhouette, style-forward buyer, New York heritage aesthetic
Fit
Boxy; size down if you want a fitted look
Norse Projects
Sigfred Merino
$220–$280
Danish design, clean Scandinavian silhouette. The Sigfred is a slim-fitting merino with slightly longer body length — flatters most builds. The Scandinavian approach: no branding, no detail work, just excellent cloth cut well.
Best for
Slim fit, Scandinavian aesthetic, everyday Scandi wardrobe
Fit
Slim fitting; go true to size if athletic build, size up if average
Drake's
Merino V-Neck
$280–$380
Drake's makes the best V-neck in the merino category. The vee is proportioned for wearing over a collar (the classic British look) without looking too 70s-academic. Weight and yarn quality are class-leading.
Best for
V-neck silhouette, worn over collar, British heritage look
Fit
Slim British cut; size up one if between sizes
How to pick — buyer's guide
What micron merino should I look for?
Under 18.5 microns = Extra fine (softest, next-to-skin), 18.5–22 microns = fine (versatile, mid-layer), 22+ microns = regular (suiting, mid-layer). For sweaters worn against skin, target under 19 micron. Uniqlo uses 17.5 micron — that's excellent for the price tier.
Is merino wool machine washable?
Most modern merino knitwear is machine-washable on a wool/delicate cycle, cold water, mesh bag. Air-dry flat. Never tumble-dry. Always check the label — some heritage mills still require hand-wash only (Johnstons of Elgin is one).
How do I avoid merino pilling?
Lower micron = higher pilling resistance. A blended fabric (merino + 3–5% nylon or polyamide) pills less than 100% merino. Washing inside-out, cold cycle, mesh bag reduces mechanical abrasion. Using a fabric comb ($5) removes any pills that do form.
Crewneck or V-neck merino — which to buy first?
Crewneck first. It works under a collar (for the layered shirt-and-sweater look), standalone with trousers, and under a blazer. V-neck is a strong secondary purchase for the shirt-collar-visible look specifically.

Frequently asked questions
What's the best merino wool sweater for men?
Uniqlo Extra Fine Merino Crewneck at $40–60 is the best value — 17.5 micron, machine washable, excellent layering piece. For mid-tier, Everlane Premium Merino at $110–140. For heritage investment, Johnstons of Elgin at $195–265 or Drake's Merino V-Neck at $280–380. All four are correct picks within their tier.
Is expensive merino wool worth it?
For heritage mills like Johnstons of Elgin or Drake's, yes — the yarn quality, handle, and drape genuinely improve with wear rather than degrading. A $200 Johnstons sweater worn for 10 years costs $0.05/wear; a $50 Uniqlo replaced every 3 years costs $0.04/wear. The numbers are close, but the ownership experience at the premium tier is materially different.
What's the difference between merino and regular wool?
Merino wool comes from Merino sheep and has finer fibres (typically 15–24 microns vs 30+ for regular wool). Finer fibres mean softer, next-to-skin feel without itch. Merino is also naturally temperature-regulating, odour-resistant, and (in modern treatments) machine-washable. Regular wool is warmer but coarser — better in suiting, outerwear, and chunky knitwear.
Can I wear a merino sweater to work?
Yes — a fine-gauge merino crewneck or turtleneck is appropriate for smart-casual offices. Pair with wool trousers or chinos and leather shoes. The Reiss Caine Turtleneck and the Norse Projects Sigfred both read professional. A chunky-gauge merino reads more casual and is better saved for weekends.
