Built for everyday urban life and versatile travel needs, the Echo offers minimalist aesthetics and practical adaptability. Crafted from 500D Cordura® and finished with reliable YKK® zippers, it combines sleek style with rugged functionality, easily transitioning between daily commutes, meetings, and quick trips. Its compact and expandable design makes it perfectly suited for both professional environments and casual outings. The Echo quickly expands by an additional 500 cubic inches (8.19L) through a discreet perimeter zipper, providing extra space whenever needed. Inside, a laptop sleeve with stretch fabric and a 1.5" elastic top securely accommodates laptops up to 11.5”H x 9.5”W, alongside an internal zippered mesh pocket to keep your essentials organized and accessible. Quick-access storage includes a convenient top pocket with a key-hook lanyard and a front stash pocket for immediate access. Designed with thoughtful travel-friendly features, the Echo includes reinforced side pockets that comfortably hold 32oz water bottles and a vertical luggage pass-through to secure the pack easily on rolling luggage handles. The ergonomic shoulder straps, inspired by our ARK platform, feature premium foam padding for lasting comfort during daily use or extended travel.
