What sank your last pair of swimmers :


Terrible shape


They took ages to dry


Itchy net lining


They lost their colour fast

Let’s Dive in

Seriously shipshape

These aren’t thigh-hugging endurance-swimmer shorts, and they’re not board-short baggies either. Our Swimming Trunks fit right. Inspired by vintage trunks of old, harking back to the glory days when poolside attire had a little more sophistication, a little less spandex. We cut these above the knee for a classic shape that works just as well if you’re clocking a few lengths at the local lido, or kicking back in the south of France.

Material world

Swimming shorts need to be light, durable and comfy, so finding the right material for the job is crucial. We actually found two sustainable fabrics that were so good we decided to offer you both of them… The first’s 100% recycled polyamide. This stuff keeps its shape and is super comfy. It’s also tear-resistant, a bonus for those of you jumping in the shallow end. Second up is a 70% Seaqual and 30% recycled polyester blend. In a poetic turn of events that should provide for superlative beach-chat material, Seaqual’s made from reclaimed ocean waste.

Plain sailing, not plain shorts

Last time round you lot scored the Swimming Trunks an impressive 8.6/10, but you weren’t thrilled we skipped out on patterned options. Well, we got the message: a holiday isn’t a holiday without colourful trunks. So we went with five eye-catching options to choose from, punchy patterns included. To make things even better, the trunks are carefully dyed to improve colour-fastness, meaning the three musketeers of the fabric-bleaching world — sun, salt and chlorine — will be kept in check.

High and dry

You know the scenario — you plop into the surf for three minutes and you’re stood around with sopping wet shorts for three hours. Not ideal, is it? Well, you’ll be happy to hear that these materials are both hydrophobic. That doesn’t mean they won’t get in the water with you, it just means they’ll dry a lot faster than your old cotton trunks did.

Smooth operator

It’s a well-known fact that itchy swimming trunks aren’t much 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 working in some triple-stitched side seams and bartacks were a no-brainer. What are these? Well, the former, as you might have guessed, are three rows of stitches that make your trunks seriously sturdy 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

We opted for a nice, secure velcro flap pocket on the back of these for your valuables. We added a little buttonhole at the bottom so water can drain out. The sea’s lovely and everything, but there’s no need to carry half of it around with you. There are also two larger side pockets, big enough for phones, wallets, sunnies - just remember to pat yourself down before you try that flip off the high board.

Firmly secured

Talking of diving boards — a bit of holiday acrobatics is all good and well, but no one likes losing their shorts on impact. We decided to spare your bushes, and went for a strengthened elasticated waistband. That means you can focus on perfecting your Olympic-standard belly flop without distractions.

A European Masterclass

Our recycled polyamide is made by the chaps at BALAS, a French family-run business that’s been making forward-thinking fabrics for over a century. The Seaqual-polyester blend on the other hand comes courtesy of the reclamation bods at Lemar, Portugal. Both materials are shipped off to Sonix (also in Portugal) who turn them into superlative swimmers. They know what they’re doing when it comes to shorts, as proven by their work on our chart-topping boxers. A Franco-Portuguese game-changer… Bacalhau à l'orange, anyone?
