I have the exo 400, 700 did not fit my head the same, and it has been a very good helmet. The only thing I dont like about it is it pushes up like its going to fly off at high speeds. Granted this could be because Im tall and above the "bubble" but it happens so Im relaying. Im looking for a new helmet over winter and really open to anything....so watching the thread post any good deals if you guys know of any
