The travel-obsessed friend has a particular gift problem: everyone knows their personality, so everyone buys them "travel stuff." Result? Three passport holders, two neck pillows they already upgraded, and a luggage tag with their name misspelled. The real chaos isn't finding the right gift. It's that they've already bought the right version of everything themselves, and what you bring from a craft fair is two generations behind what they sourced during a layover in Bangkok.
The safest bets are gear that's consumable or long-overdue for an upgrade. Compression packing cubes are one of those things most people are still using in the set that came free with their luggage years ago, never bothering to replace. A multi-country adapter (not the single-socket budget kind) is something travellers perpetually delay buying until they're at a foreign airport with a dying phone. Noise-blocking sleep accessories are safe territory too: even obsessive travellers rarely splurge on their own comfort, and since fit is personal, they'll actually use a better one.
What to avoid: anything travel-themed but decorative. A canvas tote with a world map print, a passport cover in a pattern they didn't choose, a coffee-table book about a country they visited two years ago. These gifts signal "I Googled travel gifts" more than anything else, and an actual traveller recognises that immediately. The trap is thinking "travel-themed" equals personal. Knowing someone travels is just the starting point. What makes the gift land is knowing what gap in their kit they haven't filled yet.
