I've totally converted to the tiny sub 1 ounce doo dads for 3 season use, but am wondering what people recommend nowadays for winter use in very cold climates like the White Mountans of NH.
Back when I did a lot of ice climbing and winter hiking we all used the big Petzel caving lamps, sometimes with a dangling battery pouch that allowed us to tuck the battery into our clothing layer which helped keep the battery warm and functional.
I still have 2 or 3 of these old style headlamps down in the gear room but they all must weigh over a pound easily.
What are you guys using in the winter now when the following conditions apply:
1) Sub zero F temps expected
2) Night hiking expected (but with a snow layer on the ground which makes night hiking by headlamp easier.)
