If they're not full seal they're unacceptable. That's because with a full seal there is 360 protection.

Unless of course you folks out East just dual each other at 20 paces and go home.

Most airsoft/paintball fields will allow ballistic goggles, just not safety lenses. If they don't allow it, that's their thing. There are some pretty good paintball goggles. Try the valkan tactical ones with thermal lenses. They're low-profile and don't fog easily. Paintball goggles by a paintball company but designed more for airsoft.

But paintball masks arent really a big deal, unless you want to use your iron sights, or red dot, or scope, or cheek rest, or use night vision, or basically do anything cool.

Or drinking/eating during the game....

You can drink/eat wearing paintball goggles...
