Not at all in 3 of the 5 modes.  The two Deep Sleep Modes attract comments from the self conscious but honestly nobody cares what you look like when the lights are out in the cabin at 30,000 ft when everyone is trying to get to sleep.  Many users have reported, after many hours of sleep, that other passengers tap them and ask where they got the product!  Regular neck pillows make you look like a car crash victim but because everyone is familiar with them, that joke got old quickly like this concern will too!  We think those that worry about how the product looks really haven't traveled much.  If they have, they would know that sleep, so you arrive at the other end happy, is much more important!
