Product Customer Reviews

I didn't know running pants were a thing till these popped up as a bought with and I thought I'd give them a try. My normal bamboo pants get quite damp with sweat then cold when I'm on a long run. These are great very comfortable and dry fast will get more.
Fits perfect
Lovely comfy fit in great range of colours and wash well. Great value.
Brilliant, very comfy to wear and they don’t fall down
Perfect fit. Great value for money
Nice comfortable shape and material.
I bought these as I have had them before and they didn't disappoint. They are just as good as my previous briefs. I have bought more expensive briefs but they didn't fit or feel as comfortable as these. These briefs fit well, feel comfortable when running and haven't caused me any rubbing or chaffing.
Brilliant pants! Comfortable and breathable. Worth the money
I am completely satisfied quality and look. Good for running and every day wear. Will buy some more
I am a size 10, fairly slim hipped and ordered a medium, . However, these pants dug in a left quite unsightly bulges on the sides.

I love decathlon briefs. They are really comfortable with no seams in the wrong places. I have about 10 pairs and wear them daily. They are great for camping and hiking as they are very quick drying. The only improvement I would like would be if they did a couple of sizes bigger because I put on weight.
Lovely fit and invisible lines. Perfect sizing and great price.
These are really comfy I would definitely recommend them
Brilliant. Can't even feel them when running
I always add a few of these to my basket when shopping at Decathalon, these are so comfy I've started to wear them all the time (not just for running). It would be nice to see a few different colours.

Additional Product Information
Composition
Main fabric: 85.0% Polyamide, 15.0% Spandex
Ventilation
The weave of these sports briefs is adapted for areas prone to perspiration such as the lower back: maximum ventilation for even more comfort.
Combined hot pants/briefs shape
These briefs have a ”hybrid” shape combining briefs (at the front) and hot pants (at the back) for greater freedom of movement around the groin, but more ”cover-up” and sculpting for the backside.
Product testing
Perspiration wicking: the perspiration-wicking test was conducted on each material in the laboratory to check that the fabric absorbs and transfers moisture from the inside of the fabric outward and eliminates it.WASHING: The washing and drying tests guarantee good stability (dimensional stability and colorfastness). These tests are regularly conducted by an independent laboratory to confirm that our quality standards are applied.
