The DEUTER Futura 21 SL is a backpack designed with a focus on the anatomical structure of women. The carry system has been shortened, and the shoulder and hip straps have been properly shaped to provide comfort during active excursions. This option is also suitable for shorter men, ensuring comfort even during many hours of carrying. The backpack's frame is made from lightweight stamped steel, and its material is memory-free, maintaining its proper position despite intensive use.

The careful design of the carry system with partial foam padding allows airflow on the back. The Aircomfort mesh increases breathability, reducing overheating. The interior of the Futura 21 SL consists of two spacious compartments. The main compartment allows for the installation of a hydration bladder (not included). The smaller compartment features an organizer for essential items and a hook designed for securely hanging keys.

On the outside, there are additional pockets for carrying daily items such as a water bottle, a small jacket, or hiking poles.
