I have the bv2s and it works great. I have the original bv2s which I bought as a demo, which has the old breathing mask. I need to update because brp changed the baffles on the side for better air flow. I sometimes get a little fogging bur all I do is just barely crack the mask for more air flow. I wear glasses all the time, its either sunglasses or reg. glasses at night. Love the helmut, field of view is great.
