Product details:

Traveling light with just a carry on reduces headaches and is remarkably efficient, that's why the crew at Timbuk2 created the Never Check Expandable Backpack as a go to traveling companion. The 24-liter volume hauls the essentials needed for quick trips, and the pack has been sized to fit in overhead bins on major airlines. The pack can be expanded via a wrap-around zipper when necessary to tuck in that extra jacket or pair of shoes, and internal pockets keep the contents organized and in place for efficient storage.
