took the helmet snowmobiling, expected it to have the breath deflector and chin wind guard since my last raider helmet with the double insulated visor had both preinstalled. Without these the mask will fog in cold temperatures. Ordered both as a set for $20 for the next weekend and no fogging, clear as could be. I did notice a little wind coming up near the side middle of the helmet at times, but this was on a windy day on an open lake, didn't notice the same problem when riding in the woods. Ventilation was great, and at time had to close vents as the temperatures dropped and only left the chin deflector open to keep airflow on the facemask. Good product at a great price, but factor in the breath deflector if used for winter sports.
