With 1100 lumens and weighing just 100 g, SWIFT RL is the ultimate multisport headlamp, a must-have for all your outdoor activities. Featuring REACTIVE LIGHTING® technology, a sensor assesses ambient light levels and automatically adapts the light output to your needs. Its headband is reflective so you can be seen at night. It's made in two parts to give you excellent support during your dynamic and committed mountaineering, trail or ski outings. The intuitive SWIFT RL has a single button for easy access to all its functions (ON/OFF, lighting modes and levels, and locking). You can also rely on its red light, fixed or flashing, when you need it. Rechargeable, it has a five-level gauge so you can see exactly how much charge is left in the battery.
