The RS-C100II rain slicker is custom-fit to the canon EOS C100 mark II camera. The Rain Slicker is constructed using nylon taslan material that is waterproof (1000MM waterproof rating) and breathable (1000G/M² breathability rating) to protect the camera from water and dust, and also allow the heat given off by the camera to escape.

There are clear vinyl windows that provide the camera operator with unobstructed views of the controls and viewfinder. Access to the camera from the bottom of the Rain Slicker allows the camera to be used on a tripod or hand-held position.
