For day hikes or short trips to the city, the AC Lite 23 from Deuter is a reliable companion. The padded hip belt and height-adjustable chest strap ensure that the weight is well distributed across your back. Even on warm days or during sweaty activities, the AC Lite 23 is very comfortable to wear, as your back is constantly ventilated by Deuter's Aircomfort mesh back. Efficient packing is made possible by the large zippered front opening. You can store your smartphone in a side pocket, allowing you to access it easily for a particularly photogenic view or when you need to check your route without having to take off the backpack.
