More than just a cherry on top of the ice cream.

An overshirt that works hard, so you don’t have to.

Having customers who know what they want makes our job that much easier. We thought you could do with an overshirt, so, as usual, we asked you what you’d look for in a bit of clobber like this. It didn’t take you long to come up with some features you couldn’t do without. The top four were:


Heavy fabric 


Soft texture


Tailored fit


Durable garment

Over to us

That’s heavy, man

It might seem daft to make a summer overshirt out of a heavy fabric. The clue is in the name, after all. But bear in mind, this fabric is heavy only for a shirt. Still a lot lighter than a jacket. You wouldn’t want an overshirt that’s too flimsy, anyway, as you might as well not be wearing one at all.

Weigh to go

In technical terms, the fabric made of organic cotton is 280g/m2. Or, to put things in plain English, what that number means to you is that this Overshirt is the perfect weight. Not too heavy, but you’ll know you’re wearing it. 

It’s an Alsatian thing

We took our time choosing this fabric, and eventually settled on one that’s produced in Alsace by Veclorex. It’s a region known largely for its food, wine, and dogs, but it also happens to be home to a few small mills making some seriously good fabrics. They’re a talented lot, those Alsatians.

Nothing fancy, just a really good fit

It’s all well and good having a nice bit of fabric, but if you can’t turn it into something wearable then what’s the use? That’s why we work with Vermis in Portugal, a team that knows exactly how to make an overshirt, with the same sharp, tailored fit you wanted and you’d expect us to deliver.

Old reliable

Look at an old b&w photo of some French fellas building a railway line. Chances are their clothes will be made of some kind of herringbone cloth. The way it’s woven makes it naturally hard wearing, so before you had Kevlar, Tyvek and the like, you had herringbone. We put two pockets in the front to stay in line with tradition too.

High performance

Unlike some more modern, lab-made performance fabrics, herringbone cotton feels great against the skin. As an added bonus, it looks rather nice close up, especially with the cat’s eye buttons made of resin by Italian maker Uniesse that work with both the colours and the workwear heritage.

Built to last

We all like treating ourselves to a new bit of schmutter every now and again, but our philosophy is if you buy something really well made, then you won’t have to buy another one for a very long time. The fusing for the collar and cuffs will have a thing to say in that.

Softly, softly 

You know when you buy a new piece of clothing and it’s a bit stiff, but after a couple of wears it’s suddenly perfect? That’s what the Summer Overshirt is like right off the mark. The first time you slip it on, it will feel like an old favourite you’ve owned for years.

Invest in the best

Think of the satisfaction you get from a garment that just keeps going, year after year. And yes, you’re allowed to feel a little bit smug that you wisely invested in quality to begin with but don’t overdo it. Quality is the name of the game here, and we chose a herringbone weave in particular due to its innate durability.

The team

Asphalte - la Surchemise d'Été - L'équipe

Four of us started Asphalte back in 2016. With a few years of experience in fashion under our belts, we wanted to make clothes, but not just any old clothes. Well-made clothes, designed to last, using great materials and made in good conditions. The guys we wanted to kit were our mates, who liked clothes but who weren't willing to go all out on a pair of jeans. We send them a survey to find out what they expected from a brand. Their answers were so enlightening that we opened the questionnaires up to everyone. Best decision we ever made.

Since then, you've been at the start of every clothes we make. We ask for your opinion on a product before we get busy with the design process, and that's the way forward for us.

We're not here to reinvent the wheel. We're here to make your wardrobe classics with the best materials and the best manufacturers. Above all, we're here to make things simple, stuff that you'll still be able to wear in ten years' time.

Over the last 4 years, we've gradually put together the dream team to make it happen on a larger scale. Today, there are 40 of us working to make your favourite clothes, in a quality that was once reserved for a handful of men.


We'd particularly like to thank the crew who helped us make the Summer Overshirt look its best from every angle :
