I would not recommend you waste your money on this high-end expensive water proof head lamp. There is no way to keep the straps tight, and the light keeps slipping down on your forehead. I had to finally use electrical tape to keep the strap from slipping. Also the flash control button will drive you crazy. I plan on cementing a raised button on it, so I won't have to take it off to find it.
