Beltbag?

Well when you open up the inventory,you have your normal backpack which holds 20 items.Then you have some belt type bag,and 2 other bag slots.I already have 2 bags however none for the 2nd slot.I was told it was a beltbag that could be bought in Droks but I couldnt find it.Does anyone know where I can buy/obtain one?

Merchant in Ascalon City.

You can actually pick them up in pre as well. Start another character and get you a couple. One of the collectors is right outside Ascalon by the rez shrine and collects scales. The other is outside of Abbey and wants belts.

NOPE

those are BELTPOUCHES and only one can be equipped.

you can buy the 2 additional BAGS in Ascalon post sear.

they can be expanded (the bags only) to 10 slots by adding a rune of helding to each bag
