It’s a packing habit many of us share but rarely think about—bringing far more underwear than we could possibly need for a trip. So, what’s the reason behind this common travel quirk? Let’s unpack the psychology and practicality of overpacking underwear.

Discover the Logic Behind Packing More Than You Need
When it comes to packing for a trip, underwear seems to top the list of “just in case” items. Even the most minimalist travelers find themselves throwing in a few extra pairs at the last minute. But why?
For many, it’s about peace of mind. Unlike other pieces of clothing, underwear is seen as non-negotiable. You can rewear jeans or a sweater, but the idea of running out of clean underwear feels like a worst-case scenario for most people. To avoid this, travelers err on the side of caution, often packing double the amount they might actually need.
Practical concerns also play a role. Accidental spills, unexpected activities, or a delay in laundry plans can all create situations where extra pairs come in handy. And when you’re far from home, the thought of scrambling to buy new underwear in an unfamiliar place is enough to make anyone overprepare.
Unpacking the Overpacking: Why Extra Undies Matter
Psychologically, packing extra underwear can also be tied to a sense of control. Travel inherently involves unpredictability—flights get delayed, weather changes, and plans shift. Packing extra underwear is a simple, manageable way to feel prepared for the unknown.
There’s also the comfort factor. Underwear is one of the smallest and easiest items to pack, taking up minimal space in a suitcase. This makes it an easy choice for overpacking without the guilt of taking up precious luggage space.
Interestingly, this habit might also reflect deeper cultural attitudes toward cleanliness and hygiene. In societies where fresh, clean clothes are associated with confidence and self-care, the idea of running out of underwear carries a disproportionate emotional weight.
The Unexpected Psychology of Travel Packing Habits
Ultimately, the tendency to overpack underwear highlights a universal truth about travel: it’s better to be overprepared than caught off guard. While some items can be left behind, underwear is seen as a travel essential that’s worth overpacking every time.
So, the next time you find yourself tossing in those extra pairs “just in case,” know that you’re not alone. It’s a practical, psychological, and even cultural response to the uncertainties of being away from home.
Whether you actually use all those extra pairs or not, the peace of mind they bring is worth their weight in your suitcase. Because in the end, travel isn’t just about the destination—it’s about feeling comfortable and confident every step of the way.
