When you just want to carry the essentials, the 8-litre Atom Sling is ideal. The teardrop shape keeps the pack close to your body, making it easy to navigate busy city streets. When you need to grab something, simply rotate the Atom round for fast access to the two zipped compartments. Large enough for your lunch and everyday items, it also comes with external compression straps that can be used to stash a spare layer - practical, adaptable, and comfortable!
