Tennis isn't exactly a winter sport. At least in the United States. While you may be able to track down some indoor courts to get in a match or two, it's not the same as playing outdoors. Well, Vacation has at least partly solved that problem.
The retro sunscreen brand just rolled out the Ball Boy Air Freshener. Naturally, it smells like tennis balls and sunscreen. You can freshen up everywhere from your home to your car to your office and, yes, even the tennis court. At only $5, it makes for a great stocking stuffer. Or get one for free when you buy the brand's Ball Boy Scented Candle.
You can score both via Vacation's website.
