My second pair and still as great

I have two pairs of these shorts - one for swimming and one for paddle boarding. They are a good fit (slightly tighter than the traditional fashion board shorts) which makes them ideal for swimming and the material allows for good manoeuvrability. The colour on the dark blue is really vibrant and has maintained its colour well. Velcro has held up well and the flat seams make them very comfortable even when wet. The material also effectively sheds water so they dry very fast.

Fits too tight

I confidently ordered an M size, what I take all the time... But this pair fits uncomfortably tight. Other than that, seems a good product overall.


Excellent product excellent material

Great Product and value for money

Excellent fit and stretch on the shorts and they dry real quick too. The fabric is very thin though...would have loved a little cotton added into it. Overall a great buy for not just surfing but also beachwear :)

The strap to tighten the shorts has fallen

After single use, the strap to tighten the shorts has gotten loose and almost fallen. I have lost the bill so unfortunately I cannot get it replaced. Bought it 2 weeks ago.

Hello Sahil,

Thank you for reviewing our product 8485898 - 500 long surfing boardshorts plain blue. Your feedback is important to us to continuously improve our products and your experience with Decathlon.
This boardshorts come with a flat belt without any elasticity in the belt or the drawcord that is there to tighten the waist. There is a clamping tab in the front part of the belt where the drawcord is attached which will help in adjusting the waist.

You can visit any of the Decathlon stores closer to you and explain your concern and the store will be able to assist you.

Thank you,

Comfortable Beach wear and you can go for Swim

I have used it for Swimming mainly and it does have a waterproof pocket. It is comfortable and I would have bought another, but they have raised the price from 699 INR to 999 INR. Waiting for them to lower it to old price.
