Whether you're packing up for a picnic, or heading up Ben Nevis. Hotting up? Don't fret. Our Freeflow technology allows air to flow between your back and the pack. So you keep cool and sweat doesn't build up on the back. There are 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.
