must be paintball approved. so most tactical stuff wont do, like the revisions. the lowest profile i have seen is the save phace brand. im planning to pick a pair up down the road since i dont really care for my jt spectras or the protos i have.
heres panda86's review on them with thickness comparisons

that being said, i think i remember you from last weekends game and i cant imagine it took to long for your mask to become opaque with fog, considering the warm weather. so if you really really want to run the mask, think about rigging up some fans for better airflow.
just means theres going to be one person still able to shoot back when i bust out the tear gas ... damn
