Aer’s New Travel Bags Are Its Lightest and Strongest Ever

Challenge’s eco-friendly RUV film also makes the material waterproof to 200 psi, with the textile maker claiming the fabric “performs in the harshest environments, in both sub-zero and tropical climates.”

The bottom line is this: The use of Challenge Ultra makes Aer’s Ultra Collection the brand’s lightest and strongest bags to date.

The Ultra Collection

In addition to the use of Challenge Ultra, there’s another subtle change you’ll notice in the Ultra Collection.

Instead of going with standard gray or the bright orange of the X-Pac collection, the Ultra Collection uses a muted lime green color for the lining in its bags.

Why lime green? It’s meant as a shout-out the bright green logo of Kickstarter, a nod to the brand’s aforementioned start on the crowd-funded website.
