Product Customer Reviews

Got this as a replacement for my old Decathlon pack. Great upgrade with more than enough storage
Good qurality and reasonable price
This is very comfortable. The only thing is suggest is to buy a bigger size as the sizing is a little on the small side.
This backpack is pretty awesome and comes with lots of pockets. I use this for jogging on 2 to 3 hr runs. The only let down is the bladder which I found started leaking after 3 months as it breaks at the crease points.
Great value and well priced running bag. It is comfortable and light. the bladder is a bit fiddly and i have to squeeze the valve really hard to get water out, but i like that there are lots of pockets to store things. I thought i would have been a size XL but ended up getting a M/L

Very comfortable and stays in place
I like it but the combined sizes m/l didn't work well for me and xl was too big
I have actually recommended this vest to many other people since purchasing it. I wear it on all my runs (4xtrail runs per week) and it hasn't rubbed at all. I have put it through the washing machine and it survived well. It is a good size for me because I can carry soft bottles in front, my keys go in the front pocket secure and they don't jangle, I throw a protein bar in the back pocket and put my extra layers (head wrap, gloves, etc) in the zippered section on the back. I was even able to fit my phone in the interior zippered pocket which was a surprise because phones are so big these days. Definitely glad I bought this one because it was a good, affordable starter option.
This seemed like a good hydration pack. I went for one run and the next time I went to use it one of the chest straps was unraveled (where it was stitched). I returned it no problem but they didn't have any others in stock to replace it. No idea if this was just a fluke or if this is a common issue

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?
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 choose the height of the 3 front straps - Thanks to its 2 side elastics, the bag stays so stable you'll forget you have it on when 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.
