The Lumen 600 2.0 light belt is the most powerful waist belt on the market, described as a car headlight. Easy to adjust settings make using this waist light ideal during long or fatigued runs. Fast and comfortable, the speed hook secures the belt around the waist while removing irritating buckles on the belly. In the case you might need to carry hydration, you can attach our Synaptic Waist Belt hydration pocket onto the Lumen 600 2.0. The rear pocket can carry a cell phone or any other essentials you may need on the go.
