Rockrider belt bag with hydration bladder MTB All Mountain 4 L / 1,5 L water in the test
You couldn't have come up with a longer name: The Rockrider belt bag with hydration bladder MTB All Mountain 4 L / 1,5 L water comes from Decathlon, Rockrider is their house brand. The hip bag costs just 45 euros including a hydration bladder - but it still looks high quality and well thought out. A second look shows that Decathlon has to make compromises here and there. For example, the hydration bladder does not have a valve - so the hose cannot be easily removed. The processing quality is good, here and there the materials used seem a bit thin.

Compartment layout & inner workings
The Rockrider belt bag with hydration bladder MTB All Mountain 4 L has a very spacious main compartment. There is plenty of room for a large pump, a spare hose and two items of clothing. The hydration bladder is also stored in this compartment - although a small partition with an inside pocket would be nice. The drinking bladder protrudes into the fins. You can also stuff parts of your clothing in there to accommodate even more in your hip pocket. The main compartment can be opened very wide and is therefore easy to load and unpack.
The pockets on the fins are a little smaller. Tools such as a multi-tool or a bunch of keys can easily be stored here, but the pockets are too short for large bars. The overlapping elastic band on the tool pocket is well thought out, but too weak to hold the tool when moving around the hip pocket, for example. However, this is not a problem when used on trails.
The lid compartment is interesting: Here you can find various slots and pockets for bars, wallets, smartphones, pumps with cartridges or similar things. The compartment can be opened completely and is very easy to access.
Strap & adjustment options
The wide fins of the Rockrider belt bag with hydration bladder MTB All Mountain 4 L are comfortable and reach over the hip bones. The strap could be a little more comfortable, but it is quite wide and still comfortable enough. There are plus points and deductions for adjusting the belt. This is designed in such a way that the contents of the bag are automatically compressed. This works pretty well - but the disadvantage is that the strap runs in a double layer around the stomach. This means that it can easily be made narrower on both sides. Loosening it also works, but the strap does not automatically slip through the buckle, but only when you lift it slightly. It's not dramatic, but it's still annoying while driving.
However, it should be noted that slim people with a minimum hip circumference of around 86 cm are unfortunately excluded from the group of buyers. Even for our test driver, who is 180 cm tall and has a slim build, it was close.
In action & on the trail
Rockrider's hip bag brings joy on the trail. Based on our reference content, the seat can be described as quite good, there is hardly any wobble. However, if you stuff a lot of contents into it, the hip pocket will bulge and tend to wobble a bit. The automatic compression straps do their job very well. Rockrider also does a good job when it comes to handling. Everything is easily accessible and sensibly arranged. There could only be a little more space for your cell phone.
