On long flights and public transport travels I want my head and neck feel comfortable (who doesn’t?), and I find that regular neck pillows do not provide enough comfort for me. The first one I ever liked was the gray one on the bottom left. However, after a few years of use it started to lose air while I was traveling back from New Zealand. I came across the Samsonite pillow I own now in a shop at the Istanbul airport, and it’s been serving me well for almost a year already. I recommend you try one of those and feel the difference!
