I have a really good test of the hemet now, just rode with it on for 1821 miles. It did well at 31 degrees in the snow. There was very minimal fogging around my nose with the pillock, nothing that affected vision at all. First day I wore it on the trip was 525 miles, started at 29 degrees and was 58 degrees when we stopped. The chin bar is much easier to operate than the older Shark Evoline I had. Goes up and back easy for getting drinks or snacks while on the interstate. Also when you open the chin bar it opens the main shield on like the old one, very nice. The sun shield is bigger and opens and closes easy.
Second day we started at 57 degrees and was 77 degrees when we stopped. Hemet temperature stayed comfortable at interstate speeds. In town at 77 it got warm, not enough air flow below 20 mph. That said chin bar open and back it was comfortable.
On the way home it was 54 and raining for 3 hours. It did well in the rain, no drips on the inside. I was very comfortable, and very minimal fogging near my mouth but nothing at all in line of sight.
I have 2 complaints with the helmet. First and most significant is wind noise at 75 mph. It is louder than I would like, but quiter than some of the modular helmets I have tried. I can live with it, mainly as being able to ride with chin bar open and back is very nice for me and out weighs the noise for me. For some it may not out weight the noise.
Second complaint is the speaker cut outs. They are size perfect for the small speakers that come with the Sena 20S or Sena 30K. They big speakers that come with those units will not fit with out modifications. I would rather run the bigger speakers, so I will eventually modify. That said speaker placement is good. Never an issue to hear Nav prompts, CB or music.
