Amazon Basics 21" Hardside Carry-On Luggage, Hardshell Suitcase With Wheels, Expandable For Up to 25% More Space, With Scratch-Resistant Surface, Four Multi-directional Wheels, Navy Blue

This bag is a fantastic, no-frills option that gets the job done without breaking the bank. I was genuinely impressed by its expandable capacity and how well its hardshell body protected my things, especially considering the price. It's the perfect starter bag for someone who doesn't travel frequently but still wants the convenience of a hardside carry-on. Just be aware that the handle and wheels don’t feel as sturdy or smooth as more expensive brands, so you'll want to be a bit gentle with it on rough terrain.

For those who love the lightweight, hardside feel but want a bit more style and reliability in the budget category, I'd suggest checking out the Kenneth Cole Reaction Out of Bounds Luggage. It's a very popular and affordable choice with similar features. Another excellent alternative is the Rockland Melbourne Hardside Expandable Spinner, which comes in a huge variety of fun colors and offers great value for a first-time luggage buyer.
