>>1344119Honestly, and not trying to sound macho, I took my gloves off a lot and was going around with bare hands (and head) while snowshoeing or uphill hiking in -25°C. However, I did keep my hat (toque as we say) on most of the time.
With merino underwear, merino long johns, track pants, cross-country skiing pants, thick wool socks, merino t-shirt and a plain old sweater/lumberjack shirt, plus my winter jacket, I was an absolute steam factory. I'd open my jacket and WHOOSH -- steaming. I'm sure you've heard of layering, so that you can vent perspiration. Very important that your sweat does not soak you and freeze. YMMV, depends what you're used to, etc. If you're not used to sub-zero temps, then don't underestimate it. Frost-bitten nose tips, fingertips or ear lobes really sucks.
But I know the risks and how to measure it. Standing around at night, after 5 minutes or so it was time for gloves. Handing my camera stand with bare hands (exposed metal in -35°C nighttime temps), I got "frost burn" when touching it and it hurts right away, like you stuck your hand in boiling water. Also, your battery will "die" within 10-20 minutes because it's so damn cold. Have a spare and put the other under your armpit to warm up, and that'll bring it back to life a bit.
YMMV -- I am a little chubby (5'8'', 185lbs) and never have problems with staying warm.
