Excellent product 5*

I purchased this product for my husband to use for cycling and distance running. Ample size hydration bladder. Storage pockets and waterproof compartment for phone. Great product, great price!

Mouth Piece had a hair wrapped in it!!!!! Yuk!

Item arrived in packaging with a long strand of hair coiled and caught in the mouth piece. I contacted Decathlon (with photos) who sent an automated response to return it- no apology. I needed it within the next few days so had to disinfect it myself prior to use. The hair was clearly seen, so the quality control must be non-existent.

Nice looking bag

Nice bag holds what it says it will but there is a bad after taste from the bladder pack which isn't very good at all. Therefore unsure on whether it will be used with the supplied bladder pack.

Great backpack

I find this absolutely great. Perfect bladder size for a 6 mile run in warmish conditions, was empty by the end. Fits really well and doesn't move around. Handy little pockets and the whistle is a good touch. Only negative is the zip pocket is too small for my mobile, so I need to keep my mobile either in the strap pocket or bouncing around in the main pocket bottom.

Lightweight and useful

This is an extremely lightweight little pack. The bladder is great and fits well. The pockets fit in enough for a short outing--I put in sandwiches, banana couple of buffs, water bladder, very lightweight jacket. For a longer run, or in hot weather, the bladder won't be enough, but it was fine for me. The bag fitted fairly well, but, as someone else has said, if you have boobs you might find it difficult to fasten. The front straps don't move up or down, so you can't adjust them for up or under! My straps went right across the front, and weren't uncomfortable, but for anyone larger they might have been too tight.

Do not buy if you have boobs!

There are some fantastic aspects of this item. Soft,ell-thought light, good price, well thought out pockets, the bladder is much easier to clean & dry than Camelpak, as it opens completely. HOWEVER if you have boobs, it DOES NOT FIT!! I adjusted it, and adjusted it, but IT DOES NOT FIT OVER BOOBS! It's clearly yet another products actually designed for men, and then had a "unisex" label stuck on it. Decathlon, if you read this, stick a couple of grapefruit up your t-shirt, try it on, and THEN see what you think...

Nice item

Nice item. Plenty of fluid for a couple of hours.

Excellent lightweight running pack with bladder

Delighted with this purchase. First time I have used a running bladder having previously used water bottles on a waist belt. The backpack is much more comfortable to use than a belt and quieter (once I followed online advice on how to eliminate "sloshing"). Handy pockets at the front for phone and energy gels, useful internal zipped pocket and room to stash extra layers of clothing etc. Used already on a trail half marathon and was excellent. No bounce or chafing and so easy to drink whilst running. Fantastic product, good quality and brilliant value for money.


Bought for my first half marathon trail. Impressive fit with very little wiggle after removing excess air from hydro pack! Bag has good space for waterproofs, a zip pouch big enough to secure phone, and nice pockets on straps to easily access gels etc. Only complaint would be that a soft flask to fit the 150ml pouch not provided - not that it is needed with hydro pack and for such a cheap price I don’t mind buying separate if needed.

Just at the start of my running journey at the 10k stage at the moment and am in training for a half.. perfect.

Good comfortable running sac

I use this bag without the water container just for carrying stuff for fell running and racing. Very good and comfortable. Could be improved by having a small zip compartment for keys

icon-circle-checkmark Verified purchase

Good morning Kath,

Great to hear that you are happy with this bag when out on the fells. With regards to the pocket, the bag does have a zipped compartment suitable for keys, mobile, survival blanket, etc. However I understand if it's not quite as small as you would want.

A 5-litre evadict trail bag ready for your first trail runs or short-distance trail runs:

To assist you on your first trail runs, our design team developed an all-in-one bag that is simple and easy-to-use:- Available in a single size, it can be adjusted to fit you with its adjustment straps and its ergonomic shape.- Your bag is supplied with a 1 L water bladder and a rescue whistle so that you have all the mandatory trail running equipment you need close at hand.- The information leaflet on the bag gives you advice on how to prepare your equipment.

Some information on the rescue whistle and water bladder:

The rescue whistle and water bladder are part of a trail runner's mandatory equipment. So, to make preparation easier, they are already included in your 5 L bag!The rescue whistle, which can produce 110 db of sound, is in the small chest pocket, so you can reach it easily.The new water bladder has a volume of 1 L, which provides two hours of running time between drink stations.

How to manage your water bladder

Your water bladder has a volume of 1 L and dimensions of 30 x 16 cm. Its tube equipped with a bite valve is 100 cm long so that it can be adapted to all body sizes.What is less well known is that you can easily cut the tube to the length that suits you for even more running comfort!Finally, we recommend that you fill your pouch with water between - 20 and + 40°C. Do not use it for milk or alcohol and do not put it in the microwave oven.

How to properly load up your trail running bag

- First step: put the full water bladder in the compartment at the back of your bag.- In the secure rear pocket, you can store your keys, smartphone and survival blanket.- Place your waterproofs in the rear pocket and put your bag on your back.- Tighten and adjust your bag. Then fasten the bite valve.- Store your windproof jacket in the easily accessible rear kangaroo pocket.- Finally, put your gels, bars and water bottle in the front pockets.

A very simple design for a lightweight running bag.

Weighing only 140 g, your 5 L bag is lightweight and comfortable for taking with you on your short and middle-distance trail runs.Its comfortable material, ergonomic shape and accessible pockets are great for getting at your equipment more easily when running.Its adjustment straps have a velcro: you can roll them up to minimise any discomfort when running.Most of the pockets are located at the back so that they do not compress your chest.

Unique bag tested on all body sizes.

To make things easier and more simple when discovering trail running, we designed this 5 L bag in one size. And to make sure that it fits as many people as possible, we tested it with 12 trail runners – male and female – with different body sizes. Their advice and feedback helped us to continue improving this 5 L bag.Naturally, the members of our EVADICT team wore this bag for numerous trail runs and other outings!
