Customer Reviews
Overall rating: 4.9 / 5 from 19 reviews.
Great fit and nice stretchy material which dries quickly. Very comfy.
I wouldn’t repeat the waterproof pocket though. It doesn’t actually fit an iPhone in a case, even though the pocket feels very big and bulky compared to the lightweight shorts. A nice idea - but doesn’t quite work.
Will definitely be buying again, but not the waterproof pocket ones.
Would highly recommend overall (especially as there was an issue with my first order which was dealt with very professionally).

I bought these shorts for my holiday to Orlando Florida, I have worn them at all the water parks…even put them through their paces going down summit plummet….my phone has stayed bone dry!! So impressed
Aaron B.5/5Verified
Great shorts very comfortable and does the job when on the beach or by the pool
Jo S.5/5Verified
Awesome pair of swimmers. My phone has remained dry throughout my first test run in Greece. I have been able to sit on the sun lounger for ages without feeling my backside has been attacked by a cheese grater.
Scott P.5/5Verified
great quality
Peter B.5/5Verified
Fantastic swim shorts
Ioannis N.5/5Verified
Great shorts, love them, have used them extensivley. Only negative is if they dont dry properly (as in my case when on holiday, hotel had no balcony for proper drying) they leave a horrible odour which is hard to wash out. Would be good if there was a way to deal with this, maybe a coating or soap that can be used alongside them.
Tahir A.5/5Verified
Great customer service
Daniel W.5/5Verified
Think they are a fantastic idea as I can have my wallet with me when swimming save leaving on the beach
Bit pricey but the proof will be when I use them if they work.
Will let you know April
John T.5/5Verified
Exactly what you’d want from a pair of swim shorts. Waterproof pocket is a bonus too.
Great service as well. Very pleased
