Don't Sit in Your Own Sweat
Our AirComfort™ boxer briefs are built right into the shorts, giving you light, breathable support. They move with you, not against you, so you stay cool, dry, and comfy all day without chafing.
Be Part of the Action
Stylish, super comfy and water-ready, they're the only swim trunks that are functional shorts for every day use. Whatever the adventure, you'll be dressed for the moment.
Stop Struggling With Shoelace Belts
Tired of drawstrings that vanish or turn into tight little knots? These swim trunks come with an adjustable Flexlock™ belt that actually does its job. Quick, comfy, and adjustable whenever you need, no wrestling required.
Don't Vacuum Seal Your Junk
Regular swim trunks were designed between the 1970s and 1980s. Still feels like it.
We tested lots of materials and picked the perfect one: stretchy, and won’t cling when wet. Stay comfy all day, in or out of the water.
Keep Your Precious Stuff With You
Don’t leave your valuables behind when you hit the water. The built-in waterproof Fidlock® pocket keeps your phone, money, and essentials dry and safe.
Don't Be a Pack Mule
Pack light, travel smart. These shorts combine swim trunks, shorts, and underwear. Bring back an extra bottle and less dirty clothes.

These shorts are perfect for the summer. They fit and feel great, and they dry super easy if I decide to go in the water
I recently had the opportunity to really test the shorts out on a vacation to Mexico, and they did not disappoint. The water proof cargo pocket and the light materials were perfect for the humid climate. Best thing is they are so versatile, you can wear them to beach and still look stylish to wear them out and about. Safe to say I’ll be picking up another pair in a different colour.
Quel look ! Le tissu de qualité est léger et très confortable. La ceinture velcro s'ajuste parfaitement à la taille. Quand je l'utilise comme maillot de bain, il sèche rapidement et la poche pour cellulaire est imperméable. J'ai acheté les 2 modèles, avec et sans la poche imperméable. Je vous recommande ces shorts sans hésiter.
Nice and very comfortable shorts. The quality is exceptional and they are perfect for casual wear also. I really love the material and the waterproof pocket.
These are a great add to my outdoor gear.
They are very comfortable. I've been using them in the city and on hikes and I've had a great time with them.
Highly recommend if you are looking for a multi purpose gear!
Amazing shorts! High quality materials and the waterproof pocket is my personal favorite, really usefull and it definitely works as mentioned.
Very comfortable and practical. Best shorts for my tropical travels.
I absolutely love this pair of shorts and swimming suit! The quality is exceptional; durable, comfortable, and perfect for swimming and casual wear. The design is stylish and unique, clearly crafted with great attention to detail. They did an amazing job! I highly recommend these for anyone looking for stylish and reliable swimwear. Can't wait to wear them again!
Great fit, great look, super functional. Would buy again!
Impressive design! Very comfy
They fit great, and look even better. 7/7 would buy again
I was lucky to be one of the product testers and may even been seen in some of the promotional material they filmed pre launch. I was able to see more than one prototype and the evolution of the product based on feedback received during testing. These shorts were not made in a day and have been perfected over several months of design and prototyping. Looking forward to getting one of each colour next spring.
The combo this product delivers, being both short and bathing suit, is simply great!
The material feels great, the number and depth of the pockets also great, the waterproof pocket, exceeds expectations.
I'm very pleased with this product and can't wait to see what comes next!
I was able to try on the shorts and was very happy with how they fit and looked. The adjustable waist bands are definitely great for those of us in between sizes and the magnetic pocket closed firmly. I look forward for my pair to come in.
I'm good friends with the creators of these shorts and I was lucky enough to be part of the test group! Not even a minute after putting them on, I wanted to have a pair. It was a perfect fit (I'm 5'8", 172 lbs) . Super comfortable. The material is soft, they look good (the wife approves too), and I really like the innovative features like the waterproof pocket and the magnetic fly. I've ordered 3 pairs and I can't wait to get them!

I was a product tester during the development phase and saw the product evolve from really good at conception to amazing in its final stage. Fits a bit bigger than true to size.
