On the small size, fits iPhone 12 in pocket though

So I’m 34 waist, and 5’10 and I ordered large - which just about fit, they’re still pretty tight. The zip pocket at the back is great and fits my iPhone 12 with case in - just about!


Lots of pockets, fit is on the small size

Comfort Trail Running Shorts.

Just love these shorts my go to colder weather shorts. So comfortable and all the pockets you will ever need. Had my last pair for 3yrs used for marathon, ultra's, and 24hr endurance, speaks for their durability. Excellent product.

Good trail running shirts

Good shorts at a competitive price, check size before buying as they come up a bit small.

Not fit for purpose

Hideous quality and design - these look like 2 in 1 online but are actually 3 in 1, being fitted with an additional pair of pants inside the undershorts. The seams of the pants and the undershorts are rigid and sharp edged like a bandsaw - I wouldn’t be able run a 100m in them never mind a decent trail run.

Chaffed inner leg

Did a 5k run with these shorts and the inner seam on the shorts have chaffed my leg. Won't be using again. The shorts are very small fitting as well.

These are amazing!

I love these shorts, my most comfortable shorts by far, and even better that they have pouches for gels, keys + phone.

Sooo many pockets!

Really great comfortable pair of shorts and so many good storage options, can still be worn quite low without interfering with your stride and great incorporated tight short with overshorts built in. I really like these shorts!

Outstanding shorts

I use these shorts for almost all my running and I love them. I mainly trail run and have used these in ultras upto 50 miles although I do wear them with decathlon running underwear for longer runs. The pockets are great allowing loads of storage with virtually no bounce. There are much more expensive shorts out there that are nowhere near as good

The future of shorts

I'm really impressed by these shorts, after deliberating whether to buy them for ages. The outer material is much softer and lighter than I expected, and feels more like loose lycra than the harder nylon of cheaper shorts. The pockets are great - I can fit a half full 500ml soft flask or a scrunched up t-shirt in each of the large pockets and it's more stable when running than carrying them in a bottle belt. You quickly forget them completely. I've run up to 4 hrs in them in summer and totally comfortable. Note I wear underwear underneath and may eventually cut out the inner brief, but no reason to so far.

Comfortable shorts

Fit well, true to size and comfortable, looses a star for a failing they share with a lot of Decathlon running kit, the care label is sewn to the RFID tag and to remove the tag (which you certainly do as it is stiff and scratchy) you have to remove the care label as well.

Great running shorts

The pockets are great and super confortables. I do 10k with then twice a week and I don't have any chaffing or rash.

Almost brilliant, but totally unusable

I've had these for a few weeks, and completed a few gentle 5k, 10k and today a 14k run. I had my doubts after last week, and they have been painfully confirmed today. The inner layer of three (a brief) has a seam at the edge made up of a rubbery elasticy material, wrapped in stitches. There are not nearly enough stitches to hide the elasticated stuff inside. This means the gripped rubbery elastic is next to your skin between your legs, moving around as you run. I don't think I could design a short better suited to cause chaffage. Without a close inspection, after feeling a little sore last week I used some chammy cream this week as a preventative measure for a longer run. Despite this I am now in pain. If I ran much further I think my legs may have fallen off. If they didn't, I'd be tempted to cut them off to feel better. I will not wear these again until the inner layer has been hacked out. This aside, the shorts are well designed. The pockets allow me to take a smartphone, 2 gels, bank card/house keys with a pocket still spare (possibly a small bottle or another 2/3 gels woulds fit). The cleaver design means these items are held securely against the runner so they do not bounce, in fact, you can forget they are there. Sizing seemed fine for me. It is such a shame about the shoddy friction creating finish. I have plenty of decathlon running underwear that is so well finished (and I will wear under these once I have cut out the briefs)....why oh why are these not finished the same way? I would recommend if these had no brief layer (nothing wrong with wearing separates items as long as the waist band is not too thick), but as they are avoid unless you like raw skin.

Hi David,

I am really sorry that you are not completely satisfaid with this product.Especially because this is one of our star products.
I am using one of this for my long runs and I never had a chafing from the inner of this short.
Maybe the sizing of the inner layer is not fitting you properly,but what I can propose to you is to try a little different product to this one,but still with a same carry/pocket option.
This product is Baggy short trail M black bronze (product ID 8503016),and it is coming with lose briefs inside of the short.Feel free to return the product that you are not comfortable with and exchange for this.
Please let me know if you are satisfied with the new short after.

Thank you.

Best regards,

Lightweight anti-irritation tight shorts

We developed the built-in tight shorts to make you comfortable and deliver maximum undiluted concentration during your outings and trail runs. Its ideal length, neither too short nor too long, prevents your thighs rubbing against each other. Thanks to its lining that uses flat seams, you will not feel any irritation (for your full enjoyment). Soft and lightweight, it is ideal for trail runners seeking superior comfort during physical activity... For performance and admiring the countryside

Multiple pockets: clever storage!

Ideal when you think that you don't need a trail running bag, this built-in storage waistband can be used to carry your essentials. At the front, there is an internal pocket covered with a mesh pocket. You can put your phone in the first pocket and a 250 mL water bottle in the second. The large rear pocket, which is also zipped, can also carry a 250 mL water bottle. Finally, in the 4 side mesh pockets, you can store your gels, bars, tissues, etc.

Advice on staying comfortable when trail running: the built-in briefs (to be kept or cut out)

In order to ensure maximum comfort and save weight, these loose-fitting shorts lined with tight shorts also have built-in briefs. These very soft briefs, which have minimal seams and are specially cut to be worn without underwear, provide excellent support.If you prefer to run WITH your own underwear, you can remove them and easily cut them out because they have been designed for this purpose.Furthermore, the crotch of the shorts has a stretch breathable mesh panel.

Great support for trail running comfortably

The waistband's drawcord can be used to secure and stabilise the contents of your seven pockets around your waist when running. As a result, it will not move, you will not feel its presence and you do not feel compressed around the abdomen. In addition to its simple, elegant and timeless looks, the bronze colour of the drawcord also matches the zips of the two large pockets located at the front and rear of your built-in waistband.
