Experience with Jet Heml + Bubble Visor?

Hello! I am an absolute two-wheeled newcomer and ordered a Piaggio Beverly 125ie yesterday. I also need a helmet and a jet helmet. 2 models like/fit me particularly well: a) Original Piaggio “Copter” b) Nexx X70 Groovy (My Beverly is white/brown, so these two helmets also fit visually well to the scooter) Question: The Nexx X70 Groovy has a so-called bubble visor, which extends in closed condition to the chin. A visor like this is certainly not a disadvantage. However, already when I try closed visor it has become quite warm quite quickly and it has also easily fogged. Now I assume that it will be a bit cooler when driving through the wind. However, I will drive almost exclusively in the city and also only in the warm season. Therefore I have some worry whether such a bubble visor is not too warm or whether there is not too little (cooling) Fresh air comes into the helmet. In addition, I sweat quite fast on the head. How is it, if you use such a bubble visor half open? Does this work without problems or if you have problems, because the air goes in below and cannot escape? The Piaggio would have a smaller visor. But if you can use the bubble visor half open easily, then the Nexx would be my first choice. You see… here is an absolute beginner… 😉 LG maximico
