Best Carry-On Travel Backpack: Amazon Basics vs Matein 45L

Updated 2026-03-01 | Read time: 8-10 minutes

A carry-on travel backpack needs to fit in overhead bins, distribute weight evenly, and keep your belongings organized. After testing six popular models, the Amazon Basics 40L and Matein expandable backpacks deliver excellent value without luxury pricing.

Carry-On Size Requirements

Standard carry-on dimensions are 22x14x9 inches. Look for backpacks labeled 35-45L—that's the sweet spot for week-long trips without checking luggage.

Weight matters. A backpack under 2 pounds leaves more room for actual stuff in your luggage allowance.
