Machka, telling people they are not going to experience frostbite until its 30 below is really, really, innacurate and misleading, regardless of what chart you link to.....and stating 'my nose and cheeks are still exposed,(at 30 below) as it should be '- what, exactly, does that mean? Aren't you aware some people experience cold much quicker, or may not be as biologically adapted to the cold, or conditioned to it, like you are?

I certainely reccomend a windstopper hat or helmet liner in extreme cold, most of the hats and 'clavas sold by sub-Performance or Crashbar are NOT windproof....

To minimize fogging issues, try a bandanda like a cattle rustler if your balaclava is dumping too much heat and moisture to your goggles, and breathing sideways sometimes helps keep the goggs from frosting....I too, though, think goggles are overkill for most conditions while biking or ski mountaineering. a good set of sports glasses protect the eyes, and stay clearer than goggles in a lot of conditions...what's worse, tearing eyes, or goggles you can't see through? you be the judge.

Oh, and for the conversionally challenged: converting temps, think 10 degrees of C to 18 degrees of F, and add or subtract 32. Simple as that.

10:18 +/- 32.
