The inreach mini rattles around inside the case just like the case will in what ever larger container so it doesn't seem like it would give much protection.

Perfect would be this case plus a bit of bouyancy, a foam pad or something that would allow the case to float--and a bright color to the case that would make it more visible if lost

If looking for a hard case for the inReach Mini this is the one.

But in an imperfect world, this is the best available case for your inReach

This is the best protective case for a Garmin inReach

This hard case fits the inReach mini and usb charging cable perfectly
