The Real Story Behind Spare Pair Underwear

Here’s the Real Story...

Picture this: I’m 29 years old, happily sipping my in-flight ginger ale, when suddenly—that feeling. You know the one. It hits me that my period has arrived a couple of days ahead of schedule, and I am definitely not prepared. Cue internal panic.

Luckily, I was working on a female-dominated team at the time, so scoring a tampon was easy. But what about my underwear? Should I just stash them in my bag to deal with at home? That’s a solid “nope” from me. I couldn’t exactly waltz to the nearest convenience store from 30,000 feet in the air. So… they went straight to the trash.

Not only was that humiliating (and a total waste), but it also hit me: Why can I buy tampons or pads almost anywhere, but never just one pair of emergency underwear? I could grab pantyhose or Depends, but not a single pair of undies? And so, Spare Pair was officially born.

Bringing Spare Pair to Life

After that cringeworthy flight experience, I teamed up with a full-service manufacturer and brand incubator to turn my lightbulb moment into an actual product. There were countless iterations of both product design and packaging before we finally landed on our plant-based, resealable pouch paired with seamless underwear—something that felt luxe enough to slip into, but discreet enough to stash in any bag.

Beyond just solving an awkward period problem, I wanted Spare Pair to address a major environmental concern: 11.3 million tons of textile waste end up in landfills each year! That’s why Spare Pair is eco-friendly and reusable. The pouch also gives you a place to keep your original underwear until you can wash and rewear—no more tossing your personal items into a plane’s teeny-tiny trash can.

Another Flight, Another Unexpected Visitor

Fast forward five years: I’m on yet another flight, and once again—that feeling. This time, not only was my underwear compromised, but so were my light-colored pants. Mortifying? Absolutely. However, I was armed with my Spare Pair and made a speedy restroom swap instead of sitting in a cringe-worthy situation for the rest of the trip.

It’s moments like these that remind me why I created Spare Pair in the first place. We’ve all been there—multiple times, even—and now it’s easier than ever to stay fresh and confident on the go.
