While up north in that cold got borderline frostbite. First time I have ever had a problem with my modular 1. So looking at new helmet for cold. I really like the breath e vac system on doo helmets so want to stick with them. Are the mod 2 helmets warmer them mod 1 helmets??. I have also been thinking about bv2 but have a couple of friends that have had issues with the mask stripping on theirs. Also see there is a mod 3 coming out this year but cant seem to find any info on what they changed to make those better. I am sure there are many good helmets out there but the sun shield and breath vac system on the doo helmets I really like so would like to stay with them but I am wondering if mod 2 or 3 is the way to go or go with a bv2s??? What are your thoughts.
