Made for trail runners, the Deuter Ascender 7L features ergonomoic, vest-style shoulder straps and two adjustable sternum straps for a close-to-body fit that's designed to prevent bouncing and wobbling when we're bounding down the trail. This pack is compatible with a 2-liter water reservoir (not included) and comes with two soft flasks that fit conveniently in the shoulder strap pockets for quick sips on the go. The 7-liter capacity keeps things light and simple, letting us stowe our small essentials securely when we hit the trail running (or hiking).
