3M Peltor PistonZ have the popular NASCAR connection and workers will race to wear them. The cylindrical shape is designed to fit and seal most size ear canals. The tips look like metal but are made from specially formulated foam that is so soft and comfortable that the plugs can be worn all day. There is no need to roll them down, just grip the stem and insert the tip into the ear canal right out of the canal. The biaxally-stiff stem is stiff enough to insert yet is designed to flex sideways if impacted during wear.
