Great value

Excellent pair of shorts. Definitely competitive with the luxury exercise shorts out there, for a fraction of the price. Been using them for 2 years and no complaints

Confortable and affordable

Frankly, best article you find that that price. I'm used to Decathlon from the time I used to live in France. They provide excellent articles for a very reasonable price. I still have Decathlon shorts from 2011 and they are still good to wear!! Highly recommend

My favourite running shorts

What’s amazing about this shorts is its simplicity, I notice how companies try hard nowadays to make something different to distinguish amongst the competitors and whilst they’re doing that they ruin the shorts. Why some add this internal lining?! It is really annoying and interfere with the underwear. This shorts is simple , it doesn’t annoy you with logos or unnecessary internal lining or integrated tights. Why , why the integrated tights

Cardio training shorts

I expected the shorts to be longer based on the picture but it is too short for my liking. Cloth is too light and thin.

Main fabric

  • 100% Polyester cationic

Fitness shorts or running shorts: what's the difference?

When doing fitness activities, you move in all directions. That means you need shorts that are long enough to keep you covered when you bend over or do movements like squats. When raising your legs or doing lunges, you need a stretchy, breathable fabric to follow your every move and provide good moisture management. All our products were designed to meet these needs, which are different from running!

The 360° concept: clothes that move with you!

An example? All our T-shirts feature a special cut at the shoulders to keep you moving freely. How did we come up with the idea? Our team observed users at gyms and worked with our R&D lab. And because style also matters, our designers drew inspiration from the energy of the sport to create dynamic lines. The result: Fabrics and a look that suit your sport! This is the 360° concept: high-tech enjoyment.

Are products tested before being sold?

Of course! All our fabrics must successfully pass rigorous lab tests to ensure your comfort and safety. We test them for colorfastness, resistance to repeated washing, perspiration wicking, and more. We call these our "torture tests." And after that? Is that it? No, there's more. We then have sports users put our products through the wringer. We listen to and analyze their feedback to fix what needs to be improved. Only then is your sports clothing ready!

What if i'm not satisfied with my product?

You have 365 days to return your product to any DECATHLON store if it does not meet your expectations (although maybe not straight after a workout...). You can also try out products for 7 days for free (by preauthorizing your debit/credit card, which will then be charged after 7 days) in order to be sure, when you make your purchase, you have the product you want!
