Pelican 1555 Air Protector Case w/Foam Black. This compact but tough case blows the competition out of the water and keeps your valuable equipment dry in any situation. This case uses the same great-feeling HPX2 super-light HPX2 resin and features an Automatic Purge Valve which keeps air pressure in the case while preventing water and dust from entering. With the pressure equalization valve this case keeps the air inside and the water out while balancing air pressure. Lightweight HPX2 polymer and an ever-present "egg crate" design keep the weight down so you can pack even more and with two-sided multi-layer foam inside you can fit even more. Equipped with an intuitive easy-to-use new twist-locking lid this case is ready for any adventure.
