I was so excited about replacing my under-helmet cheapo masks with a real balaclava.  It looks awesome in the pic.  Problem is that if you bring the nose part up toward the top of the nose, the breatheable, mesh area that is supposed to be over the mouth moves up too high; you can actually look at the pic of the mask and see how that would happen.  The alternative is to take it only 1/2 way up over your nose, which not only leaves too much exposed skin to get cold but gives you the smushed nose feeling (and if you wear ANYTHING that mildly smushes your nose, you may think it's ok after the first few mins but after two hours, it feels like you've run into a concrete wall with your nose).  Anyway, I don't hate the mask but I am returning it for a different one by the same manufacturer that looks a bit more suited to form-fit the human head (actually has a nose cutout; it's the 6827 model) plus I just also went ahead and ordered the  Chaos -CTR Chinook Multi Tasker Pro Micro Fleece Balaclava because I don't like doing the return thing over a period of weeks just to find what I'm looking for, so if the N-Ferno one fails me with the new model, I'll hope the Chinook an get the job done).  If you have a smaller face, the 6823 may work fine for you; it does keep you warm but not too warm, and the mouth area, when in place, allows very easy flow of air outward.  I just think this model needs some minor design tweaks.  Also, threading was coming off around the "tube" part that goes under your eyes; need some higher quality stitching or double-stitching there.
