Herno UK Guide: Sizing, Jackets for British Weather and Delivery

For UK buyers, Herno is one of the best outerwear brands for British weather, with raincoats, light down and membrane jackets that suit mild, wet winters. Herno uses Italian sizes, and your UK chest size is the IT size minus 10, so IT 50 is a UK 40, while Coveti delivers Herno to the UK by worldwide express with duties calculated at checkout.

Quick answer

• UK chest size equals the Herno IT size minus 10: IT 48 is 38, IT 50 is 40, IT 52 is 42.
• Herno trainers come in EU 41 to 45, shown at Coveti as UK 7 to 11.
• Herno began in 1948 making men’s raincoats, which is why so much of the range suits UK rain.
• Herno’s 2-Layer Windstopper is rated to a 20,000 mm water column.
• Coveti ships Herno to the UK by express from its UAE and Australia hubs, with duties calculated at checkout.
• Coveti Herno prices run from $300 for hats to $6,350 for the top coats.

Why does Herno suit British weather?

The UK rarely gets the deep cold of Toronto and Munich. What it gets is rain, wind and long months between 2C and 12C. That climate punishes heavy expedition coats, which overheat on the Tube, and it punishes unlined wool, which soaks through. It rewards exactly what Herno does best: light, water-resistant outerwear that layers.

The house began with raincoats in Lesa, on Lake Maggiore, in 1948, and the earliest coats used cotton treated with castor oil to keep water out. From the 1980s Herno built its name on very light nylon down jackets and parkas. Today it uses bonded membranes, PFC-free water-repellent treatments and its iconic Nylon Ultralight, which Herno describes as highly water-resistant with a silk-like feel. For a UK wardrobe, that combination covers almost every day of the year. More background is in who is Herno.

What size is Herno in the UK?

Herno uses Italian men’s sizes from IT 44 to IT 60. Coveti lists the UK chest equivalent on every product, so you can shop by the size you already know.

Trousers and some knitwear come in letter sizes, XS to XXL, and hats and scarves are One Size. Herno publishes a fit type on each product, mostly regular fit, with some slim, relaxed, boxy and oversize styles. Herno does not publish a blanket statement that it runs small, so order your usual UK jacket size. Size up one only if you will layer a thick jumper under a slim-fit piece. The Herno size guide has the full detail.

The best Herno pieces for UK buyers at Coveti

Every pick is full price and in stock, chosen for how it handles a British year. Browse more in men’s coats and men’s jackets.

1. Blue Long Parka in 2-Layer Windstopper

The UK rain coat, at $1,720. Polyester microfibre is bonded to a high-performance membrane that breathes and carries a 20,000 mm water-column rating, with modern proportions designed for freedom of movement. The length keeps your trousers dry on a wet walk to the station, and the membrane stops it turning into a sauna on the train. It suits the London commuter. It also comes in black.

2. La Giacca Padded Blazer in Dark Brown

The office jacket, at $1,720. La Giacca is one of Herno’s legendary classics, cut from recycled nylon microfibre with a light coating for a soft feel and a waterproof matt finish. A removable windproof bib with a two-way zip blocks wind on cold mornings, then comes out for milder days. It suits the man who wears tailoring and wants a coat that is not a coat. Read our La Giacca guide.

3. Navy Blue Trench Coat in Washington

The British classic, Italian style, at $2,080 and made in Italy. The Washington fabric is laminated, run-resistant and two-way stretch, treated to resist water. A removable bib with a two-way zip and feather padding add warmth, so it works from October to April. It suits the man who wants the trench silhouette with modern stretch and comfort.

4. Ecowool and Nylon Ultralight Coat in Navy Blue

The cold-snap coat, at $1,940. It uses RWS-certified virgin wool, made to the Responsible Wool Standard, with Nylon Ultralight, so it looks like a classic wool coat and handles damp better than one. It is a good choice for northern England and Scotland, where January is colder and windier. It suits the man who wants one smart winter coat. There is also a dark brown version.

5. La Giacca Hooded Down Jacket in Anthracite

The weekend down jacket, at $1,970. It uses the same recycled nylon microfibre as La Giacca, with a waterproof matt finish, in a hooded down shape for country walks and football on the touchline. Anthracite hides mud and rain marks better than black. It suits the man who wants warmth and a hood without the bulk of a parka.

6. Cashmere and Wool Fisherman’s Rib Sweater in Pearl Grey

The layer under everything, at $1,610. A cashmere and wool blend in an English rib knit creates a spongy, warm volume with a soft hand. It fits under a padded blazer and over a shirt, and it is what turns a light Herno jacket into a winter outfit. It suits a man who would rather layer than wear a heavy coat. More in men’s knitwear.

7. Taupe Maggiore Trainers in Suede

Made in Italy, at $1,050, in UK 7 to 11. A calf leather suede upper, Strobel construction for natural flexibility and a layered phylon and rubber sole give urban style with technical comfort. Taupe suede is forgiving on wet pavements and pairs with navy, grey and brown outerwear. It suits the man who wants one smart trainer for the week. See more men’s trainers.

8. Fisherman’s Rib Cashmere Scarf in Light Taupe

The finishing piece, at $1,080, One Size. Fine pure cashmere in a half-fisherman’s rib stitch gives volume, softness and warmth, finished with a metal Herno logo. A scarf is the cheapest way to make a light jacket feel warmer on a windy platform. It suits anyone who already owns the coat.

How does Herno compare with brands UK buyers know?

British men often compare Herno with Barbour and Mackintosh. Barbour is best known for waxed cotton country jackets and Mackintosh for bonded cotton raincoats. Herno sits alongside them as the lighter, more technical Italian option, with nylon, down and membranes in place of wax and rubberised cotton.

Against Moncler and Canada Goose, Herno is quieter. Moncler is the best-known luxury down brand, with a bolder logo badge, and is generally priced above Herno for comparable down jackets. Canada Goose was built for extreme cold and has a heavier feel, which is often more coat than a UK winter needs. Our Herno vs Moncler comparison has the detail.

Herno outerwear around the world: how the UK compares

• UK: rain and wind matter more than deep cold, so membranes, light down and layering pieces are the priority. Size by chest: IT minus 10.
• US: US chest sizes match UK sizes, and buyers in colder cities lean toward longer down coats and parkas.
• Italy and Europe: Herno’s home market uses IT sizes directly and favours padded blazers and car coats over tailoring.
• Japan: Herno has had stores in Osaka and Tokyo since 1968, and Japanese buyers often favour clean, minimal technical pieces.
• Middle East and Australia: light nylon pieces suit cool evenings and travel, and Coveti ships from hubs in both regions.
