OK yeah I was just talking about the net. I know what envelope style is, but floor style seems interesting. I assume it attaches in 4 corners and can cover the whole cargo area to prevent shifting but not sure!I think I misunderstood you. The mat folds so that is fits on the floor flat and unfolds for back seat down and another flap for both back rows down. Is keeps the carpet from getting ruined. It was already in the vehicle when I got it, folds to perfectly fit with each row.
The nettingIf it is like I had in a previous vehicle, attaches to the sides and you put stuff in or behind it to keep things from shifting. I will do photos of both tomorrow
