I bought this (size L, XL) for bicycling to work in winter (10-30 deg F) to protect my face from freezing winds (even on a calm day, riding a bicycle generates a 10-15 mph headwind). Immediately I found the neck hole to be too tight making it difficult to get it over my head. Furthermore, the face mask fits too tightly across my nose. This pushes in the tip of my nose making breathing annoyingly more difficult. Also by stretching across the bridge of my nose, the mask creates two "chimneys" on either side of my nose, exiting just under my eyes. This funnels hot moist breath straight up to my glasses, fogging them impossibly. The mask is useless as it comes. However, there is a fix (which should NOT be necessary if they would have designed it correctly). The major problem with the mask is that it does not contour your nose. What it needs is a bendable wire across its top edge to conform it to your nose in order to seal off those "chimneys" blowing hot air on your glasses. My fix was to sew to the top edge of the nose piece one of those bendy 1/4" wide plastic twist ties that come on coffee packages from the grocery store. The plastic is easy to sew and the parallel wires at each edge will bend and keep the mask contoured over your nose. Just center it across the mask's upper edge and sew it on the outside (like a very large Breath Rite strip!). I also cut the mouth covering out as it does not exhaust my breath fast enough. Things I do like in the overall design - the hinged top and mask so you can lower the mask, the windproof material, the warmth. My fix does not alleviate the too tight fit, but it does make the mask useable on bitter cold days. Goggles would seal off your breath coming up the sides of your nose, but since I need to wear glasses and a rear view mirror attached to them in order to bicycle to work, that was not an option. If they added more material to the nose piece and enclosed a bendable wire in its upper edge, to contour it (like on mountaineering parkas' hoods), this would rate five stars. As it comes, I can't recommend it for bicycling in bitter wind, unless you are willing to modify it. The truth is, before I bought this mask, what was just as effective was to tape across my nose, forehead, and temples with athletic tape (from Walmart), and continue using a conventional balaclava without the face mask. This kept the wind from freezing my face but I tended to look a bit like The Mummy or The Invisible Man. Now I look like a Ninja wearing a gigantic Breath Rite strip (my coffee bag twistie is white).
