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
Store owner replied:
Job Done! Thanks for the confirmation Jo!
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.
Store owner replied:
We like that word Ioannis, "Fantastic!" Thanks for the review! :)
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.
Store owner replied:
Tahir, thank you for the review - and also mentioning us on Facebook 😎 Regarding the odour you say you experience when drying... This is new to us, and speaking with the team it can really only be generated by what they have been exposed to. So maybe an extra salty sea, or seaweed heavy environment? Also when drying try to use the hanging loop on the rear of the short to help with aeration. But please do drop us a line if you need any help or advise or if you experience ongoing issues and we can see what we can do to help you out 😊
Store owner replied:
Cheers Daniel - we aim to please 😎
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
Store owner replied:
Do keep us posted John - so far we've got a 100% record! So kick back and enjoy the shorts with confidence and a cold drink �
Exactly what you’d want from a pair of swim shorts. Waterproof pocket is a bonus too.
Great service as well. Very pleased
Store owner replied:
Thanks for your review Ethan �� Kayaking sounds amazing, and bang on point for what we made these for! We hope you get lots of use out of these - please do send in some pics! 😎
