Since for now, this is a prototype, I cannot show more of the new Petzl Nao headlamp. Its weight decreased from 193 to 147 grams whilst its brightness increased from 750 to 1600 lumens… In case you are really interested,you can check it out tonight between 6 and 8 pm on the trails around Nagy Kopasz…
