Where to buy hard shell back pack for my P4

[ElGuapo]

I have been searching this forum with information where to buy a hard shell back pack for the P4.
Sorry in advance if this topic has already been addressed.

At the end of November we are going to fly on a domestic flight, and in February we are going to fly internationally. I already have a soft back pack which I use for my drones but I am looking for a hard shell back pack that, if I am not allowed to store under the front seat of an airplane, I can check it in and not worry about damage the drone.

Amazon. I'm quite happy with mine. Holds everything and four batteries.

Side Note: You WILL NOT be allowed to check Li-Po batteries. They MUST be in the cabin with you. (They go boom at -80°)

I've found that for most questions that start with "where should I buy...?" the answer is usually "Amazon.com".
