The onebag travel community has a reputation for obsessive optimization — and a recent packing list for a three-day trip to Sofia, Bulgaria perfectly illustrates both the practical wisdom and potential overthinking of ultralight travel.
Posted on r/onebag with detailed photos and categorization, the list reveals what happens when preparedness meets minimalism: a personal-item-only setup that includes everything from a 20,000mAh power bank to flip-flops for hostel showers, multiple charging cables, emergency medical supplies, and — somewhat surprisingly — both a tampon and a condom for a three-day solo trip.
Let's break down what's genuinely useful versus what's security-theater packing.
The Smart Essentials
Some items on this list represent hard-won travel wisdom:
Flip-flops for hostel showers: Non-negotiable. Hostel shower floors are biohazard zones. This one item prevents athlete's foot, fungal infections, and general disgust.
Merino wool socks: Two pairs for three days. Merino resists odor, dries quickly, and works across temperature ranges. Smart choice.
Running gear: The traveler plans to run in Sofia, which requires dedicated shorts and shoes. Dual-purpose packing.
Loop earplugs: Essential for hostel dorms. Snoring roommates will destroy your sleep without them.
Padlocks (2): For hostel lockers. Bring your own — hostel-provided locks are often terrible.
Microfiber towel: Hostels either don't provide towels or charge rental fees. This saves money and space.
Tide pen: For emergency stain removal. Tiny, light, saves outfits.
