When you're trail running, you need to keep liquids and energy bars within reach. The large Cross Run 2 Waist Pack has space for your supplies and a light wind shell too. Jack Wolfskin have connected the waist belt to the bag in two places, creating a tension triangle so the bag sits firmly and securely against your body. There is space for your water bottle, head torch etc in the main compartment, front pocket and two bottle holsters. To make the zips easy to operate while on the move, they've been equipped with large toggle loops.
