Zitat von Jim Evans im Beitrag #13Being quieter than the RPHA11 wouldn’t be hard. It’s a light,comfortable hat with great visibility and ventilation but it’s NOISY.
Regarding RPHA-11 noise, I completely disagree Jim, but it just shows we're all different.
It does indeed! The sound seems to come up from below, must be the shape of my neck or something. On the other hand, the hat fits and I couldn’t find many that did.
