The NANUK 903 is a compact 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 188 x 124 x 79mm giving 1.8 litres, with an external footprint of 231 x 173 x 97mm and an empty weight of 0.6kg 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 a 6.3mm shackle. It is sized to meet most airline cabin carry-on allowances. supplied empty, so it can be fitted with foam, dividers or a custom insert to suit, and backed by NANUK's limited lifetime warranty.
