Laravel 5.2 - Getting a pivot table additional attribute

I'm using Laravel to track Gear in Wearhouses. For that I have 2 tables: gears and wearhouses, and another pivot table: gear_wearhouse.

The relationship between the two tables is a many-to-many relationship, and in my pivot table, in addition to the gear_id and wearhouse_id columns, I have a qty (quantity) column.

Now I loaded all the wearhouses that store a certain gear item ($whs = $gear->wearhouses), and I want to get the quantity (qty field) from the pivot table.

How can I do that the easiest way?
