Vail, early Jan.
I am a CO native, so I had to go with the CO print. The mask is comfortable and warm, especially in positive temps.
^^ This specific day was the first I had any issues with it; -10 blue bird day. Worked at about 80% efficiency. Still froze and bunched up with moisture in the material, but when you get to negatives, anything is going to do that.
Overall, 4 out 5 for me. I'd recommend one with a couple of 'buts' in there.
