Small, Light and Bright
I've never owned a head lamp before so I can't really compare this to other models, but it seems a good design.
Features include a "lock" mode so it doesn't accidentally turn on when inside your pack, Variable brightness with 2 different bulbs (1 wide angle, 1 narrow beam), strobe mode (red and white), red light for low light situations, battery status and single button operation.
It takes a few minutes of practice to get comfortable with operating it, only one button and quite a few modes.
Only feature I would like added is that currently it goes back to full brightness when you turn it on after turning it off. It would be useful if it went back to the last brightness setting you used.
It's a given that this goes in my pack for backcountry hut overnighters, but it also goes in on day trips - You never know when you'll need it.
