You could bubble-wrap your silk underwear when you fly, or you could pick up the tough-as-nails Burton Air 25 Rolling Gear Bag to keep your underoos extra safe. Realistically speaking, you're probably interested in protecting more than just your underwear, and to that end, this rigid rolling bag is lockable with TSA-approved locks. A shovel-inspired telescoping handle makes it easy to roll this sucker through JFK (good luck finding your way around, though) and the fur lining inside lets those nosy security offices know who the real baller is.
