Exactly as the title says.
The normal behavior for environmental suits is, you equip it, and if you enable visuals, it overrides your current outfit regardless of what that outfit is. You disable it, it only overrides your current outfit if you activate the environment suit. The Burnham CQC one, however, won't override your outfit when you enable visuals unless your outfit is using the default Uniform outfit type. So, say, you have the Resistance Armor for your current outfit, you equip the suit, enable visuals, no change. Even if you activate the suit, it still won't override your costume, leading to the hilarity that is walking around in vacuum with no environmental suit visuals.
Also, comparatively minor nitpick: the suit activation and thruster buttons are flipped in the UI vs every other environmental suit in the game.
