The Camelbak Arc 2 Running Belt is a lightweight way to carry along some hydration and essentials on your run without keeping them in your hands. This comfortable lightweight belt provides the perfect cradle for two 10 oz Podium Arc Bottles. This Camelbak bottle is made with BPA-Free TruTaste polypropylene which won't add any plastic taste to your water. As you run, the JetValve self seals to eliminate splatters and spills as the bottle moves up and down on your hips or should you want to hold onto it and not place it back within the Arc 2. If you require more water, you can easily add 2 more Podium Arc bottles to the Arc 2 to double the amount of hydration this Camelbak running belt can hold. There's even a pocket on the Arc 2 for your running essentials, like your phone, house keys or an energy bar. Front and back reflectivity helps keep you visible should your run start as the sun is coming up or it takes you into the evening hours. Help keep thirst at bay on your run with the Camelbak Arc 2 Running Belt.
