And how does Purevave’s travel-friendly line compare?

This complete guide answers all your questions and helps you choose the best carry-on backpack for flights, weekend trips, business travel, or everyday commuting.

What Is a Carry-On Backpack?

A carry-on backpack is a travel backpack designed to fit within airline carry-on size limits so it can be stored in the overhead bin—or in some cases, even under the seat.

Unlike rolling suitcases, carry-on backpacks are:

• Lightweight
• Flexible
• Easier to maneuver
• Faster through airports
• Perfect for hands-free movement

A well-designed carry-on backpack keeps your essentials organized, protected, and accessible during flights.

Purevave’s backpacks—especially the Purevave Large Travel Carry-on Backpack and ExpandPro Expandable Laptop Backpack—are specifically engineered for modern travelers who want comfort, durability, and efficient packing.

Is a Backpack Considered a Carry-On?

Yes — a backpack can be considered a carry-on if it fits airline size restrictions.

Most airlines allow:

• 1 carry-on bag (overhead bin)
• 1 personal item (under seat)

A backpack can be either:

• Your carry-on, if it fits overhead
• Your personal item, if it fits under the seat

Purevave’s travel backpacks are designed to meet common airline carry-on dimensions while offering enough space for clothing, electronics, and travel essentials.

Airline Carry-On Backpack Size Rules

Airlines have different size limits for carry-on luggage. The most common dimensions are:

Standard Carry-On Size:

22 x 14 x 9 inches
(56 x 36 x 23 cm)

A backpack that stays within these limits can go in the overhead bin.

Personal Item Size (Under-Seat Backpack):

Usually around:
17 x 13 x 8 inches
(43 x 33 x 20 cm)

Purevave’s backpack sizes fall comfortably within carry-on and personal-item ranges.
For example, the Purevave Large Travel Carry-on Backpack measures:
13L x 20.5H x 6.7D inches
making it a perfect overhead-bin backpack on nearly all airlines.
