The Thule Pack ’n Pedal Commuter Pannier has an internal pocket which can accommodate up to a 15” laptop. There are two external pockets, one of which is meant for a flashing light (it’s semi-transparent so the light shows through the pocket) and the other can hold small items.
The Thule Pack ’n Pedal Touring Panniers and Tote have no internal pockets, but both have external pockets for a flashing light.
