Frequent fliers know the real perils of air travel.

Screaming, upchucking babies. Stale, germ-ridden air. The wafting aroma of beef Stroganoff. And, worst of all, the chatty, smarmy, halitosis-afflicted neighbor who mystifyingly finds encouragement in your curt one-word answers and withering glances.

Sure, the blanket-over-the-head trick will do (it has for us). But next time you fly you may want to go with a more subtle approach, like a Strawberry Jim sleep mask. The playful designs feature unorthodox pictures on the outside while giving off a definite “Do not disturb” signal. Spa has a cucumber slice on each eye. Baahh features a herd of placid sheep. Overdose has an overturned prescription bottle. And for the true go-away vibe — to be used only in cases of extremely poor hint takers — the Rock Star’s menacing skull-and-crossbones should do the trick nicely.

If it doesn’t, you have our permission to barf on him.
