Sandringham

£565.00

The Sandringham is our signature smock reimagined as a ladies' trench, built in the same fabrics as the Vintage Henry and cut in royal blue for winter. It's named after the Norfolk estate where the Royal Family spends its winters, and it's made in Britain in a small first run.

How a Soldier's Smock Became a Lady's Winter Coat

Introducing the Sandringham, the first ladies' trench coat in the Lockwood line, cut in royal blue for winter.

For fifteen years I served in the Household Cavalry. In that time I learned that a good coat isn't a luxury. On a cold parade square or a wet morning in the stables, it's the difference between getting on with the job and counting the minutes.

When I started Lockwood, I built our smocks on that lesson. Then something kept happening at shows and in my inbox. Women would try on a smock, love the fabric, and ask the same question: "Jacob, when are you going to make one for us? Something longer, something I can wear into town?"

The Sandringham is my answer.

Our signature smock, reimagined as a trench

It's made in exactly the same fabrics as our Vintage Henry smock. Nothing has been lightened, softened or swapped for something cheaper. What's changed is the cut. It has a longer trench length and a shape made for a woman, so you get the protection of a field smock with a silhouette that looks just as right at a Sunday lunch as it does on a January dog walk.

Why Sandringham?

Every winter, the Royal Family makes its way to Sandringham in Norfolk. The days there are short and the wind comes in hard off the coast. It's a place that asks a lot of a coat, so it felt like the right name for one built for the winter months. We cut it in royal blue, a deep, rich colour that stands apart from the usual greens and browns without ever looking out of place in the countryside.

What the Sandringham does for you

You stay dry when the weather turns. It's built in the same proven fabric as the Vintage Henry, the smock our customers already trust in the field.
You're covered where it counts. The longer trench length keeps the wind and rain off your legs, not just your shoulders.
One coat does both lives. It's smart enough for town and tough enough for the yard, so you're not swapping coats at the door.
You'll stand out for the right reasons. Royal blue is rare in country outerwear, and people will notice.
You'll keep it for years. It's made in small batches here in Britain, built to be worn hard and looked after, not replaced next season.

I looked at buying the Falklands Smock

I looked at buying the Falklands Smock, but was unsure with regards to sizing, so I emailed Jacob who got back to me with some good advice and reassurance about the returns policy.

Two days later and I'm wearing my new Smock, perfect fit and excellent quality piece of kit, I'm beyond impressed with Jacob and Ruth, who packed and dispatched my lovely new coat!

Jacob and his team have exceptionally high standards about their customer service, and will be around for a long time with their business standards and work ethic. Keep up the good work mate, I will be coming back!

Squaddie-Proof Gear

Squaddie-Proof Gear! Outstanding Quality, Service & British Craftsmanship!

Ordered late on Wednesday night, received a personal welcome email and order confirmation on Thursday, and by Sunday my order had arrived via tracked Royal Mail. Four days from ordering to wearing! Absolutely first-class service.

I ordered the Vintage Henry Smock, and the quality is simply outstanding. The styling is unique, full of character and a genuine stand-out piece. It’s one of those garments you immediately know is something special.

I also ordered the British Harlequin Polo, and again, the quality hits you straight away. Heavy-duty material, excellent construction and a real sense that no corners have been cut.

Sizing is spot on, too. Both garments fit true to size.

What makes Lockwood even more impressive is the company ethos. A veteran-founded British business built around quality, durability, integrity and making clothing that lasts. It’s refreshing to see a company genuinely putting those principles into practice.

I’ve always believed “buy cheap, buy twice”, and it’s immediately obvious that Lockwood takes the opposite approach. This is proper kit, designed to stand the test of time rather than the next fashion season.

Squaddie-proof gear!!! that’s about the highest compliment you can give!

Outstanding products, a personal touch and exceptional service. Lockwood has gained a very happy customer. I’ll absolutely be back for more.

Five stars without hesitation. Highly recommended!

It's a great gilet..so great I have two!!

It's a great gilet... so great I now own two (olive and navy) and also ordered one for my Nan and she's chuffed to bits! It's wonderful knowing Lockwood is supporting the British economy and I'm so proud to wear our family name out and about. I just wish my Grandad was still alive as he would have loved this timeless, quality brand and he would have loved that it's 100% British. Genuinely top quality and stylish.

Where do I begin

Where do I begin? Maybe the fantastic, personal customer service, maybe the quality of my Churchill smock. First time purchasing and blown away by the quality of design and materials used. Second to none for customer service and was also very happy to know I was supporting a former serviceman. All I can say is I will be purchasing more and will with great pride tell people, when asked, this is a Lockwood Smock.
