This is an excellent headlight! I've had another fenix headlight & this one is just as good if not better. It's lightweight but tough & waterproof! With the 3500 18650 battery it has the best runtime of any headlight I've used or heard about. It just keeps going & going! It's very easy to operate even with cold or gloved hands & has 4 main light settings & couple of red light settings. The ratchet system on the strap makes it very easy to get it nice & snug on ya head no matter what type of hat you may be wearing.
