Great and well designed

Used this for the Spartan trifecta weekend. 42km over the weekend and no problems. Really comfortable and didn't move around. Front pockets are really accessible.

No matter how I adjust it the pack bounces heaps. The mesh backing acts as sandpaper.

Great pack but sizes too big for most women

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.

Best ever - light weight

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

Great multi purpose bag!

Have used this on a 70km bike ride, 10 km trail run, and 10km hike. Definitley exceeded expectations. The material is really soft and doesn't pill your tshirt. You don't even notice this pack even when out biking for 3 hours with a full liter and some snacks inside. I'm so glad I took the chance ordering online I'm so happy with this bag. Lots of functions/details and easily adjusts for a good fit. You cannot beat the value for the price, I can't believe the bargain this was!

Perfect for my needs

I’m new to trail running and didn’t want to spend a lot of money. After searching lots of brands I decided on this one as it seemed to fulfil my needs and was a very good price. I was concerned about sizing as I am a size 8 fits perfect no bouncing or moving around. Does what it says, just perfect

I love this vest, it doesn't move or rub, it's not heavy or bulky and looks good too.

Great quality, great pricing

Bought this on recommendation from a friend. It's great. Takes 1 litre of water (or thereabouts), doesn't bounce around but sits nicely on the back (despite some sloshing sounds). I was concerned about the sizing as I am a UK 12 and this was XS/S however it fits absolutley fine. Also got a few pockets for mobile phone, on route treats etc, and a small back pack area. Just love it.

Trail running bag

This pack is so comfy and even when the bladder pack is full it isn't heavy to wear. It has so many pockets that are great for a variety of things x

10 liters and 10 pockets to carry your essentials on a trail run.

There are 6 pockets at the front so you can reach your essentials in a single move:- 2 pockets for 500 ml soft flasks- 4 mesh pockets for gels, bars and collapsible beakerThere's a secure pocket at the back to store your valuables (smartphone, keys, survival blanket), a main pocket to store your clothes and headlamp, and a big mesh pocket to keep your rain jacket always handy.

A bag designed to keep you hydrated on trail runs

With space for a 1-liter water bladder on the back (included, attached by hooking on) and 2 front pockets for 500-ml flasks, this bag allows you to carry up to 2 liters of water in total.Considering that you drink an average of 500 ml of water per hour while trail running, that gives you 4 hours of autonomy. Enough to give you peace of mind between aid stations!

So, what about the water bladder then?

Your bag comes with a 1-liter water bladder included. It's suitable for temperatures ranging between -4 and 104°F, for water: no milk, no alcohol, and no putting it in the microwave ;)As to the tube, you can cut it to whatever length you like!

A bag so light you don't even notice it

In trail running, every ounce matters! Weighing 10.1 oz when empty, your bag is truly lightweight. And to fit your personal requirements, it's available in 3 sizes (XS/S, M/L, XL) and is easily adjustable:- you can adjust the height of the 3 front straps - the 2 velcro side straps adjust the tightness of the bag. Result: Your bag stays so stable you'll forget you've even got it on while trail running.

A design loaded with details, to make your life easy

Trail running puts you in situations of extreme fatigue. That's why we've designed a bag that makes every move easy.- The water bladder tube is clipped on, so as to remain near your mouth at all times.- The mesh pocket at the back allows you to reach your rain jacket in 1 move.- The 110 db safety whistle is incorporated into a front pocket.

Never run without your poles?

Along with the whistle - mandatory in many races - which is located in the little chest pocket (hence near your mouth!), this bag also features 2 elastic straps on each side to attach your 3-section trail running poles.

Gaëtan, kalenji product manager, introduces his team of trail running enthusiasts:

”For us, it's a matter of pride to design and test our products ourselves. We wanted to make a bag we'd be proud to wear. I took part in 6 or 7 trails last year from China to the OCCⓇ in Chamonix. And the big challenge awaiting our trail team in 2019 is the Diagonale des Fous!”
