Decathlon’s Rockrider All-Mountain Bottoms look to strike the perfect balance between cost and performance thanks to a host of features including strategically placed waterproof panels, a durable water repellent (DWR) coating and stretchy fabric that’s designed to hug the wearer’s body while still providing plenty of articulation.


Decathlon Rockrider All-Mountain Bottoms details

Claimed to be water repellent – rather than waterproof – the All-Mountain Bottoms have three-layer waterproof panels on the backside and lower legs, while the rest of the trousers’ stretchy material has a DWR coating to help limit water and mud sticking to them.

Decathlon claims the material is abrasion resistant, too.

There are two thigh zip pockets, with the left-hand pocket featuring an internal organiser.

The pockets weren’t big enough to comfortably store a modern smartphone.

The waist is elasticated with two sets of poppers to adjust tightness and there is a large raised panel extending up the small of the back. The ankle cuffs have tight-fitting elasticated hems.

My size medium weighed 307g.

Decathlon Rockrider All-Mountain Bottoms performance

The Rockrider All-Mountain Bottoms size up small, especially around the waist and crotch. My 73kg, 178cm frame was at the upper fit limit of the mediums and the smalls were too tight for me.

However, the stretchy fabric meant the overall fit was comfortably snug, feeling athletic rather than constrictive, even when pedalling seated.

There was also plenty of room for knee pads and they didn’t cause the trousers to be pulled down.

The large raised back panel stopped water and muck getting on the small of my back.

The raised panel around the back of the waist stopped water and mud splashing onto my back and dripping down the back of the trousers. With baselayers tucked in and my jacket over the top, this was a great anti-weather seal.

They were also plenty tight enough to not slip down once heavy with mud and water.

The tight ankle cuffs created a good seal to help stop water splashing up my legs through deep puddles. Their stretchiness made getting the trousers on and off a doddle, too.

Generally, the DWR coating did a good job of making water bead and run off the legs’ material. They did eventually soak through, especially on the thighs, but this shouldn’t come as a surprise given these aren’t waterproof.

The waterproof backside panel resisted water penetration for longer than I was expecting, though, with water starting to soak through after an hour and a half of wet weather riding.

Elasticated cuffs stopped water splashing upwards onto the inside of the trousers.

Key to the Rockrider’s success is that once soaking wet they remain comfortable, thanks to the soft shell material – my skin didn’t stick to the inside, which helped retain heat. This made them suitable for all-day epics.

The pockets were big enough for smaller objects, but because the waist and crotch area is so tight, they weren’t comfortable to wear once the pockets were full.

There was also a fold in material just above the pockets, but it didn’t seem to hamper comfort or performance.

Decathlon Rockrider All-Mountain Bottoms bottom line

The stretchy material meant there was plenty of space for knee pads.
Ian Linton / Immediate Media

The Rockrider All-Mountain Bottoms are an impressively priced, high-performing solution to winter rides, keeping your legs warm and clean.


Unless you’re riding through streams or in torrential storms, these will keep you reasonably dry. For the price, there isn’t anything better.
