Sweltering days won't prevent your daily run when you have Nike's Double Pocket Flask Belt attached to your hips. The two flasks included with the belt hold up to 20oz of fluid (10oz per flask) which will keep you suitably hydrated while out on the road.
The Pocket Flask Belt has many features for something so simple, such as a stabilised design & form-fitting belt which curves to your body and reduces bounce, a zip pocket so you can keep your keys and valuables secure, a reflective swoosh for extra visibility in low-light conditions and a clip-on closure. The two flasks are also ergonomic, lightweight and comfortable to hold.
