This is my first non-budget helmet (I know, I know), though I know it's still mid-level. After a few hours in her, I must say:
Great airflow, never felt so much air getting to my scalp when desired
SO LIGHT! Much lighter than anything I've played with
Very quiet, as in, I worry less about permanent ear damage with these Satos
Really large visor view. The world is clear and pretty.
I went through Helmet Harbor due to their excellent customer service (the physical shop is in Gilbert). Really happy with this helmet and now I know, you can get quite a bit more when you spend more.
