The backpack works by utilizing a [compression functionality](https://www.trendhunter.com/trends/wandr-w36) on the inside where it will decrease load sizes by as much as 50%, which will thus enable it to be stowed under the seat on an airplane. The pack is paired with comfortable straps for wear on the back, but also has wheels to be easily pulled when required. The Airback FLEX backpack has a water-resistant design, TSA-approved lock and has a laptop compartment for fitting devices up to 15-inches in size. The pack also has odor-free pockets for storing shoes or toiletries. ## Trend Insights (Trend Hunter) - Score: 3.6/10 - Popularity: 42% | Activity: 14% | Freshness: 53% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Fashion](https://www.trendhunter.com/fashion) ## Key Themes ### Why This Trend Is Growing - **Compression Technology:** Innovative compression technology in luggage offers the dual advantage of space efficiency and reduced travel stress for frequent flyers. - **Multi-functional Travel Gear:** Travel gear with versatile functionalities, such as shoulder straps and wheels, caters to diverse travel needs and enhances convenience. - **Compact Luggage Solutions:** The emergence of compact luggage solutions addresses the increasing demand for practical storage options in air travel. ### Industries Being Reshaped - **Travel Accessories:** The travel accessories industry benefits from innovations focusing on maximizing space in compact luggage designs. - **Aviation:** The aviation industry sees a shift towards under-the-seat luggage as travelers seek alternatives to overhead bin space. - **Outdoor Gear:** Outdoor gear manufacturers embrace dual-purpose designs, merging travel convenience with rugged functionality. ## Related on Trend Hunter - [Modular Travel Photography Packs](https://www.trendhunter.com/trends/onepro-flex-backpack.md) - [Travel-Friendly Backpacks](https://www.trendhunter.com/trends/72hour-backpack.md) - [Organization-Forward Backpack Drops](https://www.trendhunter.com/trends/matrix-backpack.md) - [Vacuum-Powered Suitcase Accessories](https://www.trendhunter.com/trends/ekester-travelpack-vacuum-kit.md) - [Trackable Travel Tech Backpacks](https://www.trendhunter.com/trends/scapade-airpack-backpack.md) - [Contemporary Travel Backpacks](https://www.trendhunter.com/trends/bis-classic-backpack.md) - [Chic Weekend Jaunt Backpacks](https://www.trendhunter.com/trends/carl-friedrik-72hour-backpack.md) - [Earbud-Inspired Backpack Designs](https://www.trendhunter.com/trends/airpack-backpack.md) - [Oversized Earbud Backpacks](https://www.trendhunter.com/trends/airpack.md)
