As someone who is perpetually on the go—both as a travel writer and a new mom of twins—I’m always on the hunt for timeless wardrobe staples that combine comfort, style, and versatility. Enter the Spanx AirEssentials half zip and AirEssentials wide-leg pant: two oh-so-cozy loungewear essentials that can be worn separately or as a matching set.

I know what you’re thinking…Spanx? Loungewear? Yes, really. While the brand was initially known for its shapewear and undergarments, it has since expanded to offer a wide range of clothing—from denim and slacks to dresses, jumpsuits, and tennis skirts suitable for any occasion, be it the gym, the office, a long-haul flight, or, in my case, frequent trips to the pediatrician. I like to think of the AirEssentials set as a more elevated take on pajamas—though unlike the latter, these are acceptable to wear outside of my apartment. Best of all, you can (barely) tell I had less than five minutes to get dressed.

The half-zip sweatshirt stands out for its ultra-warm and seemingly weightless construction, which will keep you comfortably warm (read: not sweltering) for hours on end; as such, it’s an especially great pick for chilly plane rides. Plus, it’s ideal for layering courtesy of its oversized fit, which is why I often wear mine with a tank top underneath. Another bonus: It comes in 12 color options, from violet and black to navy and red.
