These look quite nice, but my question is, why would you want to fly in the rain?
They do look nice, they feel nice and they protect your battery and your Power Button from Dust, Pollen, Rain, Snow, and from Shifting under heavy breaking or swelling .
There are a number of threads that refer to swollen batteries while flying so the Wet Suits provide a nice tight seal to prevent that from happening.
With that said the Wet Suit main focus is on those that need to get the job done rain or shine.
Imagine you were planning on selling your Farm, you schedule your drone apt when your back in town and the drone guy calls you and says, I see some clouds can we do this next week,
Happens all the time, Drone Pilots are more afraid of the Rain than the taxes they have to pay.
Thus the best way to ruin your company is to Cancel.
We have an account in Switzerland that has a squadron of
mavic 2 that patrol the Rail ways rain or shine with there focus to keep the rail ways clear.
and the list of Companies are many.
Next on the list is Panic,
There are countless posts of those that panicked when it started raining and crashed there drone.
the Wet Suits make a lot more sense than a skin and provide some real comfort and empower your drone.
Search and Rescue : Well they need to fly in all environments.
Storm Pics: Some of us love to get them, feel them and capture them , and for that you need a Wet Suit. Lightning Pictures come to mind.
Notice how the rain rarely shows in the pictures.
When it comes to flying in the Extreme Cold the Wet Suit Provide 6 Degrees more Heat to the Battery which is critical to fly in the Cold temps as your video that you posted shows, a nice heads up for that.
