Sitting somewhere between a trail vest and a backpack, Montbell's Cross Runner Pack 15 is the ideal storage solution for trail runners who are pushing the distance. With a 15L capacity, there's more than enough room for all that race-day mandatory kit, with the breathable 3D mesh shoulders and back-panel keeping the air flowing when the heat is on. There's space for trekking poles, and those easy-access shoulder pockets are perfectly placed for keeping those life-giving snacks close to hand-whether you opt for gels or Haribo.
