Highlight: Feels more like a shirt than a pack
Ultrarunner Stephanie Howe Violett helped design the latest vest for Nathan. Body-mapped and sized to fit, this 12-liter carry capacity pack feels more like a shirt than a backpack. With two moveable elastic straps, each with three points of contact, it has a jostlefree fit, even when loaded. It comes with a 60-ounce hydration bladder.
