Streamlined and efficient, the Swift X is designed to go where you go. The Swift X is a modern take on a time-tested design. Over 10 years ago, we designed the Swift. Ten years later, we’ve added some modern upgrades to create the Swift X. Constructed from lightweight, durable fabric, the Swift X joins our premium Zero-G line. This ultralight backpack’s simple, modular design means it easily configures to become your perfect pack for any adventure, be it a quick overnight trip or a calendar year triple crown.
