Just updated my older Kalenji backpack. This has more easily reachable pockets at front, my Kalenji bottles fit better and with the different size options it fits even better.
I have tried top of the range vests this does everything for a fraction of the cost. I never use the bladder in these bags, perhaps an option without, lowers the cost and the waste.
Great pack but sizes too big for most women
Used for 3 to 6 months
I love this pack. I've used it to train for and run a marathon. In addition to the bladder I use a 500ml silicon water bottle in the front. Plenty of space for gels, snacks, raincoat and your wallet. My only dislike is the sizing. I have the xs/s size and it's slightly too big, even with the straps tightened as far as they go. I am 175cm and 70kg - bigger than the average woman - so I think most women would find it too large. Decathlon I recommend you review your size range.
Perfect Trail bag for starters.
Used for 7 to 12 months
I have now used this bag for approximately 600 miles of running.
I took it on all my training runs getting ready for Race To The Stones (100km) it carried all gear required.
I recently completed Hardmoors Goathland 28 miles and it carried all mandatory kit and then my “what if” kit.

My typical run pack has:
First aid kit, Poop kit, Jacket, Gels, Salt tabs, spare socks, cup, snacks, poles, tape.

Two negatives I found are:
The hanging loop stands up and touches the back of my neck, which after 30 miles ca get on your nerves, simple fix, I cut it off.
Secondly the loops designed for carrying poles don’t much like the telescopic style of collapsing poles and only really hold folding poles well enough.

In summary a great starter bag with many pockets, some hard to get to without removing pack but holds all you need on a budget.

I have given 5 stars as it’s a bargain.
Used for More than 2 years
Used for 3 to 6 months
Recently bought for a 30 miler - fitted all the compulsory kit and there was still space for the usual gels etc. The front has 4 adequately sized pockets for easy reach food, phone, maps etc. I was really impressed for the price and would definitely recommend.
Best ever - light weight
Used for 2 to 8 weeks
It seems small but it fits so much in - this got me through my 250km run will all daily supplies - its a must for any ultra
Used for 2 to 8 weeks
Ran in it a few times with both bladder and soft flasks in those front pockets. No serve slogging and acceptable, but the largest pocket on the back with a zipper is impossible to use without taking the entire vest off. So the pockets left for storage with easy access is very limited, need to wear those versatile running pants to increase storage space for large smart phone and other items.
Surprisingly, I manage to put a larger 2 litre bladder into the back pouch, so don't know why it comes with a 1 litre bladder
Overall, it is acceptable for the price but do expect to stop for the supplies stored at the back unless you have a monkey arm.
Really good piece of kit. No problems so far.
Used for 1 week or less
I've not used a running pack/vest before, but found that when I get to 7-8 miles running in the heat I'm pretty dehydrated. I did some research and the branded ones come in at around £60, and I'm not in that place. I've also started buying Decathlon trainers, and they are good, so why not? I have the M/L size. I'm about 40-42", and this fits me fine, but if you are much bigger in the chest, this might not be a good fit for you. Try one on if you can. Also note that the chest straps can move up and down on a kind of ladder system. I guess you might be also to extend them somehow. It sits high on your rib cage, nothing across the waist. It comes with a 1 litre water bladder which hangs securely in the back. Tube feeds out via a shoulder strap. I've still getting used to that. Enough space in the back for a thin waterproof, spare socks, etc, but its not a ruck sack. You'll need to buy front flexible bottles separately. Lots of hoops to clip stuff onto, and pockets for gels or whatever. I've done 2 x 6 mile trail runs so far and it is just fine. I'm really please with it. Works way better than I expected and (compared to other specialist ones) a bargain.
