Turn darkness into light with the Duo S from Petzl! With a maximum output of 1100 lumens, this head torch is extremely bright and simply ideal for any activity at night where you need to see the ground in front of you. There are three different beam types, with one covering a wide area, one focused beam and one softer beam. Plus, the unit comes equipped with clever Face2Face mode, which decreases beam strength to avoid blinding others. The elastic strap, the additional strap over the head and the external battery pack make for a comfortable, balanced and no-slip fit. The rechargeable battery, which is included, provides the unit with the necessary power. Last but not least, the dial can be operated when you have thick gloves on as well. Regardless of whether you're in a cave, deep snow or mountain biking, the Petzl Duo S will light up the dark!
