TUSITA Cradle Kit Accessory Compatible with Garmin inReach Messenger Plus Satellite Communicator - GPS System Accessories

This is not ul or cheap, so I hesitate to rec it here... but when I don't have a good pocket to put it in (my day hiking vest/bag does, my backpacking bag not so much), I have mine on this. NiteIze also has these mini lanyards that may work.
