Who it suits

Choose this Deuter 21L hiking backpack for day hikes, walks and active outdoor use when ventilation and a shorter back fit matter. Check the back-length and body-height guidance before ordering, especially if you prefer a standard-fit pack.

Aircomfort ventilation

The Aircomfort back system creates a gap between the mesh and your back. The flexi spring steel frame supports steady load distribution, while ActiveFit shoulder straps and stabilizer straps help keep the pack aligned for day-hike use.

Practical 21L organisation

The pack combines a compact 21L capacity with stretch exterior pockets, hip-fin pockets, a top pocket and an internal wet compartment. A rain cover is included, and the pack is compatible with a hydration system up to 3L; the reservoir is not included unless separately stated.

For a ventilated, compact day-hike setup with a shorter back fit, the Futura 21 SL keeps key carrying and organisation features in a practical 21L format.
