Travel Set in gray color. Necessary items for your comfort during your trip include: mask, pillow and earplugs. The pillow in the set is "petal-shaped", which helps provide proper support to the neck as it surrounds and stabilizes it, preventing harmful body tilts. If you are bothered by the lighting and want absolute darkness to enjoy an undisturbed sleep, then the sleep mask is the right choice for you. Additionally, earplugs have the ability to reduce or even eliminate noise levels from external sounds.
