40 Genius Carry-On Hacks That Make Traveling So Much Easier

36. Carry a Collapsible Water Bottle

Staying hydrated while traveling is crucial, but empty plastic bottles are wasteful and bulky metal ones take up space. A collapsible water bottle is the perfect solution. Empty it before going through security, then refill it on the other side to save money and reduce plastic waste. When empty, it collapses or rolls up to fit almost anywhere in your bag or clip onto the outside, ensuring you always have access to water without sacrificing precious packing space.
