Pelican Pelicase 1150:
The world's toughest watertight protective cases. Pelican cases feature an exclusive 1/4" neoprene o-ring to guarantee a perfect seal. Neither dust nor water can penetrate this barrier. All Pelican cases are absolutely airtight. The exclusive built-in o-ring sealed pressure purge valve allows for quick equalization after changes in altitude or temperature. Pick 'n Pluck foam included unless specified. Larger cases are by special order only.
