Customer Reviews
Overall rating: 4.3 / 5 from 15 reviews.
Really comfortable, love the no webbing and phone pocket, and the friendly and helpful response when I phoned the office
Bought for my husband who agrees it’s a brilliant idea. He went swimming with a tissue in his pocket 1st time of use & it came out 100% dry! Now swimming with his phone and loving it!
It arrived with a mark on it, but this washed out. Apart from that, they’re a nice pair of shorts / trunks. The waterproof pocket is a touch bulky, but apart from that very nice.
I did contact the help team regarding the mark and they were helpful.
Store owner replied:
Hi Toby, thanks for the reveiw. And also being awesome about the mark - we are gladf to hear it washed out just fine. We will send you a little something for the inconvenience of that issue. Cheers mate!
Store owner replied:
Paul, thank you for your review - although I do feel a 1 star review is a little harsh maybe 😕 We will provide more styles as we grow, but for now we clearly only sell the styles and lengths of products we have and clearly state on the website.
Store owner replied:
Thanks for the stars Szilard!
The pocket felt uncomfortable when sitting and the inside leg is short.
Also I have returned them over a week ago with an accompanying letter and email and I have not heard anything from Randy Cow. Disappointed
Store owner replied:
Thanks for your honest review Claire. We have investigated this and (as we have replied to you via email too) your parcel was delivered, but it appears it was damaged and arrived torn open, and your letter must have been lost. And as this return was not initiated through our Returns Portal, we had no way of really knowing who the parcel was sent by. We apologise for this frustration, but we have of course issues your refund now ✌️
Store owner replied:
Thanks James - we appreciate the waterproof pocket is noticeable, but it does need to be, in order to be 100% safe and secure. We hope you have got used to it and enjoy the shorts now!
The waterproof pocket is too prominent on the side when you st down making it uncomfortable to wear the shorts except for swimming. Would be better placed as a rear pocket.
Store owner replied:
Thank you for your review Andrew. We are sorry the Waterproof pocket wasn't great for you, we will be bringing out two new versions of shorts over the course of the next year which will include an alternative pocket to the current solution. We hope the rest of the items you ordered were up to the standard though!
Store owner replied:
Thanks Robert - we're glad to hear they were well received!
Fits perfectly. The inlay feels very comfy on your skin and keeps everything in place.
The waterproof pocket is great. It’s easy to open and keeps everything dry.
Store owner replied:
Thanks for the review Sandra - the size guide is pretty bang on, on the product pages. So it is always recommended to have a peep there first! 😊
Quite simply. I have an expensive mobile phone which is critical to my business and personal life, which I normally leave on the beach or poolside. It’s open to light fingers. Now, I put it in a totally (I’ve used it loads) waterproof Randy Cow swim shorts pocket. It fits perfectly. Before purchasing I’d recommend checking your phone size, mine is an iPhone 15 Pro Plus. If your phone is bigger, it may not fit. Best to check.
Overall an awesome product, well worth the price.
The quality is excellent and price well worth it.
