Thanks to the INTENSE hydration belt, we carry the essentials with us in our trail running training sessions. Designed with Team Sidas Matryx, it is available in four sizes to choose from depending on the size of our shorts. We love its great functionality and especially the removable stick holder. We carry our soft bottle in the large stretch compartment. The two mesh pockets on the sides and the zipper pocket serve to carry snacks and essential things such as keys, attached to the included key ring, or smartphone, in the provided case. Equipped with an emergency whistle, this trail running belt is made from 100% recycled polyester. Adjusts with an elastic cord.
