Impressed with the AGV K6-S, firstly it s very light compared to other helmets at this price point, it is also well made, the vents have a decent motion and easy to use with a glove and they work well as you can feel the airflow, changing visors is easy and the ability to lock in a slightly open position is great. I found you do get a bit of buffeting at speed but this can be due to various factors. Can t really comment on noise as I use earplugs and again can vary bike to bike.
