[SmG Batman]

I'm going with *guess the obvious* Batman and Batgirl here. 
Why? Because Batmans costume is what? Black. He is active around which time? Night. Camouflage, get it? 
And plus his costume has enough space to store all his gadgets. You need the best suit if you are up against literal gods everyday. 
Also, Batgirl has a very nice utility belt too which can store quiet some stuff and looks to be flexible enough. So her too 
Wbu?
