Bring all the gear you fancy. And switch up the back length so it?s dead comfortable all day ? whether you?re packing up for a picnic, or heading up Ben Nevis. Hotting up? Don?t fret. Our 3D Freeflow technology allows air to flow between your back and the pack. So you keep cool and sweat doesn?t build up. There?s also plenty of pockets here to help you load up for a great time outdoors. Plus, it comes with all the bells and whistles. Including a whistle. Just in case.
