This is a trail running hydration belt that prioritises comfort:
In order to provide extremely comfortable running gear, our design team developed a belt that you slip on like a pair of shorts. Or over your shorts, to be precise. In addition to being stable while you run, it is easy to adjust. Thanks to its tightening straps at the hips, just pull to tighten or loosen the belt in a single step, even when running at full speed.
Enjoy your trail runs under the sun:
By carrying the bare necessities in a belt, this frees up your back. This major plus in terms of comfort is particularly pleasant when you are running in hot weather. And with 2 x 500 mL of hydration, i.e. 1 hour of running time, your belt is suited to average outings. What's more, the attachments for your folding poles and race number are just what you need for competitive events.
How to load up your 2 x 500mL hydration belt
To start, keep your phone and survival blanket safe in a zipped pocket at the back. The large rear pocket (in the middle) is for your wind jacket, while the small one (at the bottom) is for a cereal bar. You can store the rest of your gels and cereal bars in the 2 front pockets. Then, it's time to put on your belt, like a pair of shorts! Adjust your belt and insert your flexible flasks, poles and race number!
Here is some advice on making the most of your trail running belt:
For more stability when running, we recommend that you wear it "low on the waist", i.e. on top of the hips. The flask pockets have a pull-tab for more easily replacing the flasks. You can also loosen your belt a little for more easily inserting your flask. And if your poles are also fastened to your belt, you can rotate it to gain access to your flasks. Try it for yourself!
Gaëtan, trail running product manager at Kalenji, tells the story of the design of the 2 x 500mL hydration belt:
"We wanted to offer a comfortable solution for trail runners who run without a backpack. The belt provides excellent support, while also freeing up the back. The idea was to have a compact product at the waist and we used the feedback of our customers to perfect the tightening system. In my opinion, it is a good-looking product and the testers loved its innovative features. If you always follow convention, nothing changes."
