Query: a really uncomfortable accessory

This B+W 82mm Slim-Line Circular Polarizer is really uncomfortable because the original cap lens don't fix wit the filter. The filter has his own cap, too flexible so fall down all the time, finally you lost the cap and any possibility of protection for the filter.... THIS IS A REALLY PROBLEM when you work outdoors.
