Fat Pizza clothing

Question: I cannot remember the brand of clothing that Habib and Rocky wear (mainly in the series)

Their yellow tracksuits with the gun on them.
Better yet, anyone know where to purchase them from?..

Also, a song question: The song when the gang is being 'sneaky'... I've head the song is called "Gangsta Hit" By "Big Blue"... I cannot find it on the internet, can anyone please share it to me?..

Thankyou very much.
