I was very pleased with this helmet. The construction is fantastic for the price. I briefly owned another full face helmet I bought from Hn'R, a much more expensive one and returned it due to weight and lack of good ventilation.
This helmet is actually so lightweight, I almost forgot it was there. Never felt like my head was being weighed down.
The ventilation is also something that surprised me. with 15 vents, the airflow feels great when you're riding, and never felt too hot.
The Large size is quite snug on my 59cm dome, and I could see people with larger heads finding it too tight.
Overall, for the price, this is one great helmet. I would highly recommend it as a first full face helmet or replacement for an old one.
