Most cycling helmets are pretty light. What I have is your typical cycling helmet with a small visor in the front, the kind you would find at any bike shop. I don't think it's bulky, so if that's what you are thinking of I don't know that there are many other options. The one pictured above looks like a serious sports helmet for intense mountain biking or even tricks. If you are just commuting, you can just get a regular one.
