Derek Jeter reveals his favorite underwear at pop-up store

If you're like many New York Yankees fans this off-season, the burning question concerning Derek Jeter doesn't have anything to do with with his bum ankle or how he wrangled a $12 million contract out of Hal Steinbrenner.  It's all about his undies.

The Yankee shortstop let curious fans in on what’s going on underneath his pinstripes at Thursday’s opening of Frigo’s pop-up store in Manhattan's Meatpacking District, according to the N.Y. Post.

Yes... pop-up underwear store ... in the Meatpacking District.

The Yankee slugger is a fan of the brand’s RevolutionWear skivvies, which run $100 each and feature an inside pouch that can be adjusted for a customized fit. 

But don’t expect Jeter to appear in an ad in his high-tech, high-priced undies — dubbed by some as the “TempurPedic banana hammock” — anytime soon. “It’d be too embarrassing,” he told Page Six, noting he is pals with the brand’s Mathias Ingvarsson.

Off the field, Jeter has a new gig with Simon & Schuster, Jeter Publishing. “I am interested in people’s stories,” he told Page Six. “I like to read about success stories but, more importantly, when the end result is success, the failures leading up to it. I think a lot of times people see success stories and people automatically assume they started there. I like to see the whole process.”

From now on, it sounds like his lady friends can expect some lively reading material next to the autographed baseball in his infamous swag bags the morning after.
