Love these shorts

Great shorts. Don't ride up, lots of pockets and have a drawer string.

Perfect marathon shorts!

I bought these shorts for a marathon this year as I didn't want to carry a belt or backpack. I managed to fit 5 gels, my phone, headphones and tissues into the pockets and they didn't move around or ride up at all. The length is great if you cant wear short shorts but get too hot in leggings. If anything, they are slightly large - I wear a UK 10 and the XS was fine. Would recommend!

Amazing shorts

Loads of pockets. Super comfy and great on larger thighs!

Game changer

Tried these out for the first time yesterday. They are a complete game changer for me! Absolutely brilliant. I hate taking belts as the bounce around far too much. I was able to take my phone, which I don't usually do. It fits comfortably in the back pocket, with no movement. The shorts were secure and the drawstring meant no bounce. Super comfortable. These are my new summer running essential! :)

Running shorts

They are great they have loads of pockets at various sizes and have a tie string waist. They come up a little in the large size and I would prefer them slightly tighter on my legs but not an issue.

Not for me

I bought these specifically for the convenient front waistband pocket, handy when you don't want to crush your phone if you fall.over on the trail. However, the pocket at the front was nowhere near big enough to hold a pretty standard size phone ( I have a galaxy s7) Also I have rather wide thighs compared to my much smaller waist,(I'm about a size 10, sometimes 12 in trousers) so the fit on these weren't great, the hems on the legs were really tight and cutting in to the skin. I think this has more to do with my shape, rather than the design of the shorts. I love the style and the several pockets, but it just didn't work for me.

random sizing but good shorts

Bought a pair of these last year and thought they were excellent (although they could do with a gusset rather than the lumpy seam joining). Loads of pockets in useful decent sizes and positions, and great quick drying material. BUT ordering this new pair proved impossible due to the 'new sizing' which bears absolutely no relation whatsoever to either the website sizing guide or the size of the pair I already own. After 3x cycles of delivery/exchange I finally got the right ones. the old size M is the new size S... well, sort of, but not quite... but it'll do!

Kalenji shorts

Can only order these online​..I checked the decathlon size chart to be on the safe side....well thinking that the medium would be size 12, but no they turned out to be a size 14. So when I tried them on I thought ok not much muscle support but they should be ok....went running in them for the first time and I felt as if they were going to fall down...not good for a long run! Yes maybe I should have returned them for a smaller size but I thought they would be ok.

No complaint at this price!

Overall good although my mobile cannot be fit in the pocket. I think the pocket is too small for the general mobile size.

My favourite running shorts

I love this shorts. They are comfortable to wear and i love the back pocket as it is large enough to store my phone. The other pockets are great to hold keys or a spare hair tie.
