Seriously shipshape

Our Swimming Trunks aren’t ultra-tight speedos, and they’re not big baggy board shorts. Inspired by vintage swimming trunks from the glory days of laid-back beach-attire, they’re cut above the knee for a classic shape that works just as well when you’re clocking a few lengths at the local pool, or kicking back in the south of France.

Material world

Good swimming shorts need to be light, durable and quick-drying, so finding the right material for the job is crucial. We opted for a fabric made out of 100% recycled polyester. Not only is this stuff friendlier on the environment than regular polyester, but it also manages to be super light without compromising on strength.

High and dry

You know the story—you go in the sea for three minutes, and you’re then stood around with wet shorts for the next three hours. Not ideal is it? Well, on that count you will be happy to hear that our Swimming Trunks are made of hydrophobe material, which means it dries faster than your old cotton pair.

Smooth operator

It’s a well-known fact that itchy swimming trunks aren’t much no fun, so we made sure our mesh lining was smooth, soft and comfortable. On top of that, it’s made from recycled plastic bottles. Isn’t technology brilliant?

Sturdy seams

Thrashing about in the ocean and scrambling about on rocks can be pretty harsh on swimming shorts, so triple-stitched side-seams and bartacks were a no brainer. What are these? Well, the former, as you guessed, are three rows of stitching to make some seriously sturdy seams and the latter help take the strain on key stress points. Both are classic features from the vintage workwear world and perfect for using on hardy beach gear.

Pockets a’plenty

There’s two handy hand pockets on the front and a nice and secure velcro flap pocket on the back for your valuables. This pocket has a little buttonhole at the bottom to help the water drain out. The sea is good and everything, but there’s no need to carry half of it around with you.

Firmly secured

Everyone loves a good ol’ plunge off a diving board—but no one likes losing their shorts once they splash down. To keep your shorts firmly in place, we strengthened the elasticated waistband, meaning you can focus on perfecting the perfect Olympic-standard belly-flop.

Live and let dye

Sun, chlorine and salt can cause colour to fade fast, so we made sure our dye was fully fixed and up to the task. These shorts are made to last, so it only makes sense that the colour sticks around too.


Our recycled polyester comes from the fine folk at Balas, in France, a family-run business that’s been making forward-thinking fabrics for over a century. The trunks are put together by Sonix in Portugal, the same lot who made our supremely comfy Boxer Shorts. They most definitely know what they’re doing when it comes to working with legwear that goes above the knee. You could even say it all went swimmingly...

The Team

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.
