From your alpine start, through miles or multiple pitches, and until you drift off to sleep, you need to be able to see. The Storm 400 offers a powerful beam for spotting your partner in the distance, yet balances it with three night modes so you can adjust the color for the conditions at hand. Brightness Memory lets you adjust the power of the light and come back to the same beam, while PowerTap technology boosts brightness at the touch of a button.
