Knog Quokka is a new headlamp model that joins the family of Knog silicone headlamps. It was developed primarily for running, hiking, camping and other activities and is characterized by its ultra-light weight. The Quokka's body and strap are made of matt silicone, which does not weigh down the hair. It is easy to clean, adjustable for a head circumference of 300 to 660 mm and the silicone strap can be adjusted using a clamp buckle. You will appreciate the practicality of the model thanks to the easy USB charging, built-in battery and one-button operation. There are 4 modes and 4 brightness settings for illumination.
