The AC Lite 14 SL hiking/trekking backpack from Deuter is now even lighter and features the Aircomfort back system for maximum ventilation. The SL models are specifically designed for women, with narrower shoulder straps and a shorter back system. Smartphones, trekking poles, sunglasses, or snacks can be quickly stored in the elastic and breathable side pocket as well as in the designated loops. A bicycle helmet can be secured on the outside of the backpack. Additionally, there is a provision for attaching hydration systems of up to 2 liters. It is the perfect companion for day hikes.
