The Sunriser Run Vest 8 is one-part vest, one-part backpack. The 8-litre pack is designed to hold everything you need for a long day on the trail, while the bungee system can hold extra snacks, a water filter or an extra layer you can pull on when the temperature drops. There are five pockets in total consisting of two snack pockets, two water bottle pockets and a secure-zip phone pocket. And if that wasn't enough space, there's a trekking-pole carry system on the rear of the backpack for steep uphill sections and hilly terrain. Side compression provides a custom fit for your torso and minimises bouncing when you're running. Plus, with two 500-ml soft flasks included and a 2-litre bladder pocket with internal routing for a hose, you won't be short on hydration.
