Taking a big whiff of those boxers in your suitcase — unsure of whether they’re clean or dirty — can often lead to severe nasal pain. Outlier’s Doublebag ($48) eliminates the need for your nose’s detective work with its double-walled design, letting you store your clean clothes on one side and the dirty garments on the other. The Doublebag expands as needed and also acts as a laundry bag, pillow, and pretend human body to throw in your trunk or bury in the yard with a rusty, ketchup-stained shovel.
