The new AC Lite, which also comes in a women-specific version (SL), is the ideal companion for day hikes. Our popular hiking pack is now even lighter and features our Aircomfort back system for maximum ventilation. A large zipper opening down the full length of the front provides an excellent overview of contents. A cell phone, snacks etc. are easy to access in the stretch mesh side pockets. And a helmet holder can be attached using dedicated docking loops on the front. SL Women's FitOn average, women's backs are not quite as long as men's. The SL carry system is thus slightly shorter than that of Deuter's standard rucksacks. Aircomfort System1.

The patented Deuter 3-side ventilation reduces the loss of fluids by up to 25 %.2. Ergonomically S-shaped shoulder strapsFit like gloves - comfortably padded and with Soft-Edges3. Robust and reliably tensioned back mesheven under load. It is guaranteed by a lightweight frame made of break-proof spring steel. Extremely resilient and permanently elastic, it always jumps back to its original shape after deformation.
