hey ladies!

what helmet do you wear when you are mountain biking? currently i wear either of my two road bike helmets.... but i've been looking at a "mtb specific" helmet with the little visor.... i've been looking at the giro xen (it seems kind of big).... the specialized decibel (which is really a duo purpose one... but the visor looks good on it!).... the bell sweep XC or bell slant (but i've not tried those on... just like the look of them from reseaching on the web)

anyways..... what do you all wear?
