Bought a second pair after finding the first so good. They are well made and fit great. Love the ‘no mesh’ lining, as makes them comfortable even after getting wet. So happy bought that first pair.
Great shorts love the inner pant and the quality is fab, the colours are great as well.
Hi R Munns, we're thrilled you love the HydroMotion Swim Shorts! Thanks for the kind words about the quality and colors. Enjoy your swim! 😊
Waited a little while to write the review as I wanted to use the swim shorts first.
They really are the most comfortable swim shorts I’ve ever owned, they’re stylish and very well constructed. There is one drawback which is why I didn’t give them five stars. Unlike other swim shorts they just don’t dry very quickly. Despite sitting in 36’ temperature it was over three hours before they had dried however the waist was still damp. I’m hoping with age the material will become better at losing water.
Hi there! Thanks for sharing your experience. We're glad you find the swim shorts comfortable and stylish. For quicker drying, we recommend hanging them inside out. Hopefully, over time, the material will improve in drying speed. We appreciate your feedback!
They fit well, feel amazing, look good and are from a B-Corp. I love them. The only downside is how long they take to dry and are quite heavy with the water they hold when wet/damp. That’s a pity, but they’re still fantastic.
Hi Luke, we're thrilled to hear you love the swim shorts! Thanks for the tip on drying — hanging them inside out can help. Enjoy your swims! Best, Swole Panda
Good fit, comfy lining. Love the print
Hi there! We're thrilled you love the fit, lining, and print of the HydroMotion Swim Shorts. Thanks for sharing your positive feedback!
Essential wardrobe upgrade. Game changing swimmers!
Hi there! We're thrilled to hear you love the HydroMotion Swim Shorts. Thanks for the awesome review!
Look smart in and out the water and no discomfort when wearing a wet suit. So glad I got two pairs in different colours
Hi Mark, we're thrilled to hear you love the swim shorts! Thanks for your fantastic review and for choosing Swole Panda. Enjoy your swims in style!
Love wearing them so comfortable !
Hi Daryl! We're thrilled to hear you find the HydroMotion Swim Shorts so comfortable. Thanks for sharing your positive experience!
Great service and great swim shorts. I was a bit nervous about buying these but I doubt I’ll go back to my old swim shorts having worn these for a couple of weeks. I can highly recommend.
Hi Max, we're thrilled to hear you're enjoying the HydroMotion Swim Shorts! Thanks so much for the kind words and recommendation. We appreciate your support!
Very stylish and comfortable - I bought two pairs of swim shorts and was very happy with them
Hi Richard! We're glad to hear you find the swim shorts stylish and comfortable. Thanks for your support and happy swimming!
I mistakenly ordered incorrect size, one email and problem sorted. Staff were very helpful and the size I should have ordered arrived within a few days. Swim Shorts are great quality and so comfortable.
Hi Kevan, we're thrilled to hear you had a great experience and love the swim shorts! Thanks for your kind words and for choosing Swole Panda.
Loved the swim shorts, lining made them super comfy for a full day on the beach!
Hi there! We're so glad you enjoyed the comfort of our HydroMotion Swim Shorts. Thanks for sharing your experience!
I bought a pair of the HydroMotion shorts for a holiday and ended up ordering a second pair before we'd even flown home. The boxer-style liner is a game changer, no scratchy mesh, no chafing, even after a full day on the beach. They dry really quickly too, so you can go from the pool to lunch without feeling soggy.
The zip pockets are properly secure and the hidden phone pocket is a brilliant touch. They feel far more expensive than they are, and knowing they're made from recycled materials is a nice bonus rather than the whole story. Comfortable, smart enough to wear to a beach bar, and clearly built to last. Highly recommend.
Hi there! We're thrilled to hear you love the HydroMotion shorts and that they made your holiday even better. Thanks so much for your kind recommendation — we really appreciate it!
Very nice bathers which are comfortable and long lasting. I didn’t find the quick drying claim to be entirely accurate, but wasn’t looking for this feature anyway. The order form defaults to size large - make sure you change your selection before ordering as it’s costly to send them back.
Hi Gerald, thanks for your positive review! We appreciate your feedback about the sizing and quick drying. We'll look into the website issue to improve your shopping experience. Glad you like the swim shorts!
Not used yet but looking good
Hi David, glad you like the look of the shorts! Hope they perform well when you try them out. Thanks for your feedback!
I really dislike swim shorts with a mesh lining. I find them uncomfortable and chafing. After some searching I came across Swole Panda lined swim shorts so I took the plunge and bought some. After a week of beach and river wear, I'm really happy with them. They look good and feel better. A great buy.
Hi Simon, we're so happy to hear you're enjoying the HydroMotion Swim Shorts! Thanks for sharing your experience and for choosing Swole Panda. Enjoy your beach and river adventures!
Fantastic swim shorts - my husband loves them! Very comfy, the inner shorts are 100 times better than mesh. Great quality and they look amazing. Zipper pockets are a brilliant bonus and rare to find. Will certainly buy again!
Hi Jenna, we're thrilled to hear you and your husband love the swim shorts! Thanks so much for sharing your positive experience. We look forward to serving you again!
Fed up of itchy, constricted netting in your swim shorts?
These guys have just the job. A 2nd layer you don't spent half your time in the water readjusting around your nethers!
Hi Dave, we're thrilled to hear you love the HydroMotion Swim Shorts! Thanks for sharing your positive experience. Happy swimming! 😊
The shorts arrived quickly and the cost was justified by the quality of the product. Very comfortable and quality material.
I bought two swole panda swim shorts for my holidays and I have to say I found the shorts excennet quality and fit. The inner lining is much more comfortable than traditional net lining. There was a slight problem with delivery which Stacy in customer service sorted out immediately .
Excellent prpducts and excellent customer services
Hi Niall, we're thrilled to hear you loved the swim shorts and appreciated Stacy's help! Thanks so much for your kind words and support. Enjoy your holidays!
Love these - really great design, comfy and well made
Hi Julian, thank you so much for your kind words! We're thrilled you love the swim shorts and appreciate your support. Enjoy wearing them!
The product was great but I inadvertently ordered the wrong size and, despite contacting the company via phone and email, nothing could be done to change it before dispatch. The result was an extra £6 to send an item back which i and they knew I didn’t want
My mistake i know - but the customer service could be a lot better, and the very least you could do is expedite my refund.
I now buy boxers, socks and swimming trunks from Swole Panda. All come with great, interesting designs but more importantly with fantastic quality at a very fair price.
Hi Richard, thank you for your fantastic review! We're thrilled to hear you love our designs and quality. Looking forward to serving you more great products!
I’ve been using these on holiday and they’re much more comfortable than the usual lined shorts. Small gripes/suggestions - the navy blue is actually quite shiny so looks a little cheap. Also I would buy another pair if you did a shorter version. These are mid length and I prefer shorts mid thigh
Hi Joseph, thanks for your feedback! We're glad you find the shorts comfortable. We'll pass your suggestion about a shorter version to our team. Appreciate your support!
I've always struggled with being a bigger guy and having to put up with ridiculously baggy shorts to get my legs in, but these fit perfectly. The liner is great and they're very comfortable and easy to move in while being streamlined fit. Definitely getting more
Hi Gareth! Thanks so much for your fantastic review. We're thrilled to hear the HydroMotion Swim Shorts fit you perfectly and meet your expectations. Looking forward to your next purchase!
Brilliant swim shorts. Very comfortable, great fit and design. Highly recommended.
Hi Vanessa! We're thrilled to hear your husband loves the swim shorts. Thanks for the kind words and recommendation!
