- Pockets for 2 soft 500 mL flasks
- Waterproof zipped pocket for your smartphone
- Velcro pocket for your gels and bars

A bag designed to keep you hydrated on trail runs

With space for a 2-litre water bladder at the back (included, attached by hooking on) and 2 front pockets for 500-mL flasks, this bag allows you to carry up to 3 litres of water in total.
Considering that you drink an average of 500 mL of water per hour while trail running, that gives you 6 hours of autonomy. Enough to give you peace of mind between aid stations, even in ultra trail!

So, what about the water bladder?

Your bag comes with a 2-litre water bladder included, 38 x 18 cm in size. It's suitable for temperatures ranging between -20 and +40°C, for water: no milk, no alcohol, and no putting it in the microwave ;)
The tube is 100 cm long and you can cut it to whatever length you want!

A bag so light you don't even notice it

Available in 3 sizes (XS/S, M/L, XL) and easy to adjust:
- you can adjust the height of the 3 front straps
- the 2 straps on the side pockets adjust the tightness of the bag Result: your bag stays so stable you'll forget you've even got it on while trail running.

Loads of design features to make your life easier

Your tube is held in pace by a magnetic attachment: it goes back in its place automatically when you let it go
- The kangaroo pocket at the back lets you access your rain jacket in one move
- Your smartphone is within easy reach, in a waterproof zipped pocket at the front
- The 110 dB safety whistle is incorporated inside 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, the Evadict product manager, tells the story behind the 15 L ultra trail running bag:

We wanted a bag that'll take you to the end of your trails in complete safety and that can carry all your mandatory gear. We took our customers' opinions into account, for instance adding the smartphone pocket.
We designed it for ultra trail, the most demanding category there is. Then we did two series of protocolled tests, which yielded excellent results.
We're proud of this product, we spent a lot of time working on its stability, compartmentalization and accessibility.
