Even if you don't need them in a carrier, these panels are an excellent idea.
They can be cut down and used as a liner for your brief case, clip board, even the driver and passenger doors in your car or truck.
In the Gunco tradition, D-R is a pleasure to do business with and I recommend his products.
You guys carrying a briefcase or a 3-ring binder/planner should really consider these panels. It could save your life.
