Measured my head at 59cm and brought a Medium (55 - 59cm) Lazer Blade helmet which was the only lid I could find which didn't give me mushroom head. Without tightening it up from the front to back I can feel a slight pressure on my forehead, it's not painful but I am aware of it and it does give me a nice red mark along it when I take it off. Tightening it doesn't make it worse, just takes up the slack at the sides.
Would I be better off going for the next size up or does this sound ok?
