For posh jet setters, this cashmere cable travel set from Ralph Lauren is as luxe as in-flight accessories gets. The set comes with a pillow, a blanket, and an eye mask, all made of the designer Ralph Lauren's signature cable-knit cashmere. There are several colors to choose from (red, beige, black, navy, and grey) and for an extra $10, you can have each item monogrammed. And the whole set can be easily stored in the pillow, which doubles as a zip travel bag. Now that's cozy.

COST: $395 at Ralph Lauren.
