Truly light makes for true light.
Our lightest outdoor headlamp weighs not much more than a thick woolly hat and offers lumen strength which some torchs have to warm up for. The MH6 is also particularly user-friendly. It also warns you when the battery level is getting low and its transport protector prevents it from unintenionally switching on in your bag. The only things you have to do is turn it on and off, occassionally charge it - and purchase it of course.
