I took the sunshade off after the first ride. It flopped up and down and made too much noise. POS.
The clear shield will not stay up on a hot day at speeds over 50 MPH or in gusty winds.
I use the N-42 as a cool weather helmet, it is superb in that role. I will retire it until fall once the weather gets hot. I think it is as good as a 3/4 helmet gets.
