Hey everyone. Well this is another really cool thing. I got this travel pillow and its a lot different from any other I've seen. Usually you either have a plastic thing you have to blow up or have a bulky not very travel friendly styrophome balls. Also they are generally the horseshoe shaped kind that for around your neck and honestly don't do much for the back of the neck support just the sides minimally too because if it was tight enough for supporting your neck it wouldn't be comfortable. This one is different for one it seems to me more like a filled up space bag.
