Bought for my son, these shorts are well made and have good features like the phone pocket
These shorts are well made, waterproof, practical and comfortable. A bargain at this price.
Very comfortable shorts over 4-5 hours of trail riding.
The shorts had a rip in them. I'm amazed it was on the shelf available for sale when it was defective. Now I have a long drive back to return. Best to carefully look over garments before purchasing

Sportingly,

Excellent product, great quality. Good value for money.
Great shorts for my very day commute to work. They fit perfectly and are really comfortable
Size is about 2-3 sizes too small

Go true to size
The shorts themselves are great, they fit well are comfortable, strechy and pretty nice. However the phone pocket is HORRIBLE your phone and whatever you put in there will bop up and down as you pedal (its fine while you go down though. I would recommend getting a different one from Decathlon but probably a different model.
Too small, not great quality
Good quality shorts but lack of pockets and maybe buy a size larger
Very comfortable, but undersized. Would definitely go a size up on normal fit.
Just bought a pair in large size. The outer shiets are a great fit but the inner shorts are very tight particularly restrictive around the thigh. I don't wont to go up a size as the outer shirts won't fit. Will probably buy a separate inner shirt on a better size.
I have purchased similar shorts from Decathlon in the past and am a medium. Website states that the medium size is 93 to 98 cm as does the label on the shorts. On receiving the shorts they are far too small, I measured the shorts as being a 76cm, which is 17cm smaller than advertised.
Good shorts a pity about the liners The shorts are well designed and comfortable with well placed pocket The liner seem a strange shape so I wear my older inners with the shorts

Keep your gloves to hand!
When mountain biking, gloves are often the last thing you put on and the first thing you take off. These shorts have a buckle on the waist so you can keep hold of your gloves without having to rummage around in your pockets. You can snap your ST 100 and ST 500 gloves on them using the press stud to keep them handy at all times.
A bit more about these shorts...
To help you get the most out of your rides, these shorts are made from 2 fabrics: a stretch fabric to follow your every move and a durable fabric to prevent snags and tears. They are also lightweight and breathable for better moisture management. And to let you move around freely, the waist is elasticated so that it fits you nicely. The shape is designed to avoid the crotch getting caught on the front and back of the saddle.
All you need, in your pocket!
To have everything you need when you head out for a ride, these shorts have clever pockets: - At the back there's a zip-up pocket for things like keys, credit cards, etc. - There's a zip-up waterproof pocket on the back of the thigh that's easy to access (even with one hand) and positioned to protect your phone from falls. - There are 3 places along your thigh for storing cereal bars: simply push down to get them out.
Shorts, undershorts, pad? here are our tips!
Your ST 500 shorts come with removable undershorts so you can change undershorts without changing everything. And of course, your undershorts act as underwear! When you buy them, the shorts and undershorts are attached. But before you set off on a ride, remember to detach them! Why? Because each has their own role to play: - The undershorts stay tight against your skin for comfort and support. - The shorts let you move around as you ride.
