Although is very expensive, but clearly the best neck pillows on the planet

We bought 2 sets for a long plane trip and the pillows since in regular use - Whether used universally for afternoon nap on the sun deck, as lumbar support in the car, as headrest in domestic bed.
After gaining experience with inflatable advertising and neck croissants and other crap applies here: "He who pays too little, pays twice".
We would buy these things at once.
