The NANUK 918 is a mid-size waterproof hard case built to protect valuable equipment in the field, in a vehicle or in transit — optics, thermal units, cameras, drones, tools or documents. Interior dimensions are 378 x 249 x 218mm giving 20.6 litres, with an external footprint of 429 x 328 x 236mm and an empty weight of 2.9kg thanks to the impact-resistant NK-7 resin shell. The case is rated IP67 — fully waterproof and dustproof — and carries an automatic pressure release valve so it never seals shut under changes in altitude or temperature, with a working range of -29°C to 60°C. PowerClaw latches with integrated slide locks secure the lid, and reinforced padlock eyelets take an 8.6mm shackle. It is sized to meet most airline cabin carry-on allowances. supplied with a cubed foam insert that can be picked out to the shape of the equipment carried, and backed by NANUK's limited lifetime warranty.
