I use a headlamp every day and I really like my Fenix HL30 for long battery life, uses AA's, buttons are easy to use with gloves. It has a red beam I like to use in my treestand before dawn as it seems to help with night vision.
The problem I have with it on a backpacking trip is it can be difficult to change batteries in real cold weather (especially in the dark).

That is when I use the Zebra light.
