[Upgraded 90° Adjustable Beam Angle] We have upgraded this running light with a brand new original design, featuring a 45° up and 45° down adjustable beam angle. This allows for excellent illumination of the ground and slopes while significantly reducing glare reflected back into your eyes. The rotating adjustment feature lets you see further, thus avoiding hazards on the road. And unlike headlamps, it doesn't wobble around, as it sits almost in line with your center of gravity.

[Lightweight and High Performance] Wearing the light on your chest solves a key problem for runners who dislike headlamps, as they can be very uncomfortable and prone to slipping due to sweat. In contrast, our chest light is much lighter (only 160 grams) and less noticeable when moving. More precisely, you can intuitively grasp the switch position of the chest light, whereas it's almost impossible to operate a headlamp at first glance; you have to try it carefully.

[Reflective and Adjustable Shoulder Strap] We have equipped this light with an adjustable, flexible strap for most morning joggers, suitable for various body types and comfortable to wear. Reflective strips placed after the white light and the red warning light provide an extra layer of protection and ensure you are visible to oncoming vehicles.
