WaterField Unveils Enhanced Air Porter Carry-On with Customer-Inspired Updates

The updated underseat bag adds customer-driven upgrades, including a new larger size alongside the original, a lightweight ECOPAK™ option, new security features, and improved organization. It preserves legroom and the original design and features that made it a company top seller.

SAN FRANCISCO, March 24, 2026 /PRNewswire/ -- Responding to the evolving requirements of modern air travel, WaterField Designs introduces the refreshed Air Porter Carry-On, an underseat personal item updated through direct customer feedback. This enhanced travel bag offers significant improvements in security, organization, and material options, all while maintaining its compact footprint designed to fit under most airline seats and preserve legroom.

The development of the refreshed Air Porter Carry-On was inspired by its 10-year anniversary and direct customer feedback gathered through a dedicated Community Design process, the same process followed to create the original bag. The company invited all interested customers — longtime Air Porter users, frequent flyers, and prospective buyers — to share ideas for refining the underseat bag to meet up-to-date in-flight needs and habits of business travelers. This process ensures that the Air Porter continues to meet modern travel demands while preserving its award-winning core design.

"The Air Porter has been one of our most trusted bags for ten years, so the goal wasn't to change what already worked but rather to ask customers what we could do to make it even better," said company founder Gary Waterfield. "We kept participants involved from ideas through prototypes, gathering feedback along the way. The result is an even more capable, intuitive travel bag."

Customer-Inspired Enhancements

The updated Air Porter introduces a second size with an additional 2 inches of depth, offering added capacity for overnight or weekend trips while still fitting under airline seats with room for travelers to stretch their legs, a key advantage over many underseat bags.

A new ECOPAK™ sailcloth option delivers strength and durability with cross-ply reinforcement and PFC-free waterproof backing, at a fraction of the weight of traditional materials. Made from 100% recycled components, ECOPAK™ uses no solvents, fluorocarbons, or ovens, reducing CO2 emissions by over a pound per yard.

As more travelers carry both laptops and tablets, WaterField added a padded tablet sleeve that fits a 13-inch iPad with Magic Keyboard alongside the laptop compartment. Designers replaced open pockets with zippered Monolite™ translucent pockets to keep small items secure and visible.

A Faraday-lined RFID-blocking zippered front pocket helps shield passports and bank cards from electronic skimming in busy airports and on crowded commutes. A discreet AirTag pocket lets travelers track the bag if needed.

The front pocket continues to accommodate the optional Air Caddy, which transfers to a seatback pocket for handy in-flight access. Designers also added pen slots, a hand-sized pocket, and a key tether.

Customers increasingly carry larger water bottles and requested side pockets to match. The upraded pockets use deeper pleats and snap closures that expand or contract to hold a range of bottle sizes securely.

Despite these updates, the Air Porter remains immediately recognizable. It retains its silhouette, underseat-friendly dimensions, and core features, including a TSA-friendly compartment, multiple carry options, and a structured interior.
