The yellow, waterproof 904 Hard Case without Foam from Nanuk is a small crushproof hard case made from lightweight NK-7 resin that protects and stores compact gear, such as a mirrorless camera and lens or a two-way radio with accessories. To protect your gear within the case, an optional multi-layered cubed foam insert is available with pre-scored squares that can be individually removed to accommodate the shape of your gear.
