i don't commute to work, however, i figure it would be proper to ask the question here.

i've been riding around during lunch.. fast pace 8-11 miles round trip. where i'm at, there quite a bit of pollen and i'd hate to have those buggers go in as i breathe.

so what kind of facemask would be good for that and also for avoiding sucking in the fumes from cars and trucks?

i know there are many out there, but i'd like to find one that is breathable so i don't suffocate as i climb...
