Overview
An 18x14x8 inch backpack sized to the personal-item limit used by most budget airlines, built for carry-on travel with a dedicated laptop sleeve and compression straps.
The airline-approved sizing is the main selling point here, aimed at travelers trying to avoid gate-checking a bag or paying a carry-on fee. It functions as a daypack outside of travel too, though the compression straps and wet pocket point squarely at trip use.
- 18x14x8 inch personal-item sizing
- Padded 15.6 inch laptop sleeve
- Waterproof wet pocket
- Luggage pass-through strap
Who it's for
Suited to travelers who want one bag that clears personal-item sizing and still holds a 15.6 inch laptop, a change of clothes, and a few travel essentials. Less useful if you regularly need to check a laptop larger than 15.6 inches.
Pros and cons
- Sized to fit under most airline seats
- Padded 15.6 inch laptop sleeve
- Side compression straps adjust capacity
- Luggage strap slides over a suitcase handle
- Personal-item sizing can vary by individual airline
Performance notes
Compression straps on the sides let the bag cinch down or expand depending on how full it is, while the breathable mesh back panel, adjustable shoulder straps and chest buckle are meant to keep the load stable over a full day of walking through an airport.
