Monoprice Inc. Koah Weatherproof Hard Case with Customizable Foam 10 x 9 x 7 Inch

What the case is and who it suits

The Koah Weatherproof Hard Case is a compact protective shell built for action cameras, camera bodies, lenses or ammunition. Its impact- and ultraviolet-resistant polypropylene body meets an IP67 rating for dust and water ingress. The fully customizable foam interior lets you cut precise cavities for each item, adding a tailored layer of shock protection. It is not for buyers who need larger internal dimensions or built-in dividers beyond the foam.

Behaviour under sustained load

The case maintains its seal and structural integrity during extended exposure to harsh environments. The IP67 rating guarantees protection against dust and submersion in up to 1 meter of water for 30 minutes. The pressure relief valve equalises internal pressure gradually, preventing vacuum lock after altitude or temperature changes. Contents stay cushioned by the foam even after repeated impacts or vibration over long journeys.

Thermals, noise and power draw

As a passive storage container, the case draws no power and produces no noise. The polypropylene shell resists ultraviolet degradation, so prolonged sun exposure does not weaken the material or compromise the seal. The rubber-covered handle stays comfortable to grip in hot or cold conditions. No active cooling or electrical components are present, eliminating any thermal or acoustic concerns.
