Not actually seeing one but I pretty sure there a standard military grade pelican case. Unbreakable, watertight, airtight, dustproof, chemical resistant and corrosion proof.
I've flown several times with mine, and it's been great. There was an issue with transport early on that they've remedied with a subtle change to the way the arms fold up in the case. I've had mine in several airplanes, and in/out of the cargo hold of an RV numerous times during a filming trip across the USA.
