Using very cool thermal formed fabric foam, Rans has designed a seat bag that doubles as a briefcase.
The case is specially designed to hold a laptop computer in padded protection via an internal pouch.
The briefcase also features cell phone, pen and calculator pockets. It is made of 1/4" formable foam and skinned in tough nylon. It comes in black with a mesh attach system that slips over the top of the seat.
A pull out built in raincover is also included.
The case can be detached in seconds either by removing the mesh or releasing the buckles.
