The NeckSnug™ Luxury Memory Foam Travel Pillow is very comfortable. My one issue with the neck pillow is that it has an elastic carrying strap which poses a strangulation risk; if you’re going to buy the pillow, you should cut off the strap. The NeckSnug is made out of memory foam and has a microfiber cover that you can unzip and wash. The pillow is 12.2 x 11 x 3.9 inches and weighs 4.8 ounces.
