I have worn my helmet in cooler temps. Kept my head from getting too cold. Very comfortable and I look quite stylish. Only concern is riding against the wind on a windy day makes quite a bit of wind noise. More so that other helmets. I love the ability to look my helmet on my bike so I dont have to carry it around. Make sure you measure your head first. You dont want to wear too tight or loose. The neck strap feels good. The clasp is a bit tricky.
All I can say is that this helmet is great for the mere fact that you can make adjustments accordingly to the size of your dome with a a simple twist of a turning knob. Not to mention aesthetically it's a pretty cool design.
I love this helmet, very stylish and cool. Was available for prime, arrived the next day. Happy with the service. It comes with some extra pads and a dust bag. Im a girl so i got the size small, fits well. Happy riding!
