The One-Bag Travel System: Indefinite Travel With Only a Personal Item

Travel for a weekend or a year with one bag that fits under the seat.

One-bag travel removes friction, not comfort. This 20-page guide shows how a well-chosen personal-item backpack can carry everything you need, using better fabrics, a laundry routine and a repeatable packing system. Airline size limits are current as of October 2026.

What's inside:

• 7 core principles and a bag-choosing guide sized to real personal-item limits
• 6 ready-to-use packing capsules: warm, cold, business, shoulder season, digital nomad and ultralight
• An airline personal-item size chart and TSA liquids rules
• A sink-wash laundry method and common mistakes to avoid
• A fillable pre-trip checklist and post-trip audit

Best for: Minimalists, digital nomads and anyone tired of checked-bag fees.
