The HeadLamp expertly blends a light, compact construction with powerful performance. With its 3D SlimFit headband which incorporates the electronics, the stretchy moisture-wicking band ensures a slimline fit that looks and feels great. The USB-rechargeable design means no batteries are required.

Seven light modes provide plenty of lighting options, with a maximum beam distance of 85 metres. The 425 is the middle product in BioLite’s series of head torches and carefully balances power with weight. It is ideal for mountain hikes, trail runners and general adventurers who need expert levels of lighting control to help them stay safe in after dark adventures.
