60 days to change your mind The AC Lite 21 SL is a women's hiking backpack from Deuter.
Equipped with a taut mesh back combined with the Aircomfort technology, this backpack offers maximum ventilation and reduces fluid loss by up to 25%. Thanks to its flexible spring steel frame, the back will return to its original position to guarantee long-lasting comfort. The abdominal and shoulder straps are ergonomically designed for comfort and good load distribution.
Very handy, the AC Lite 21 SL has pole clips, a rain cover, a ventilated and zipped side pocket, or something to store your wet clothes in. This special women's model also has a shorter back, narrower straps and a belt specially adapted to the female body shape.
With its casual look, this light and airy backpack is ideal for day hikers and beginners in outdoor activities.

Aircomfort Back System:
- For small to medium volume backpacks used on easy terrain, Deuter relies on maximum ventilation. The wear-resistant core element of the Aircomfort systems, which has been reliable for decades, is the continuously elastic spring steel frame. It gives the special aerated net a stable tension even under difficult conditions and thus creates a ventilated space between the bag and the back, through which moist air can freely escape. Fluid loss is reduced by up to 25%, increasing endurance and improving circulation (verified by scientific tests conducted by the Hohenstein Institute).
SL Fit - Shape adjusted to the female body type:
- Shorter back Women's backs are generally shorter than men's. The carrying systems of the Deuter SL models are therefore shorter to better adapt to the female body shape.
- Narrower straps. The straps have a pronounced S-shape and rounded edges. They are narrower and closer for a perfect fit on the shoulders, without pressure points or rubbing.
- Conical hip stabilisers. The hip stabilisers form a cone to fit the female shape perfectly.
