I have a feature. Again, I must be between sizes as M too small and L just a bit to big. However, has not been a real issue in the winter as riding with an Enduro skull cap under it!
My beef with it is that if I am in a forward leaning / attack position and I lift my head to see what the chuff is going on the back of my neck pushes up on the back of the lid and causes it to move forward. More of a problem when not wearing a skull cap though.
Good lids though but not that eay to fit DX lights too!
