I tend to get headaches very easily from tension on my head, particularly headbands and glasses. My first helmet was very cheap and uncomfortable, as were my first cycling glasses (both from Performance). I ended up caving and spending the extra money on a Lazer helmet which tightens all around your head instead of creating pressure points. It absolutely will not bounce around. I also got slightly nicer cycling glasses that aren't tight on my temples. Both have made a huge difference. Good luck!
