Backpack DEUTER Futura Air Trek 45 L — unisex mountaineering pack, 45 L (expandable to 55 L), 2 kg, top loading, black

DEUTER Futura Air Trek 45 L is a unisex mountaineering and trekking backpack designed for multiday hikes and alpine approaches. The pack offers a 45‑liter main capacity with an expandable option up to 55 L, top loading access and a lightweight construction of approximately 2 kg. Its air‑circulation back system helps reduce heat buildup and improves comfort during extended carrying, while load‑adjusting straps and a shaped hipbelt distribute weight for better balance on technical terrain.

Advantages

The backpack combines breathable suspension with a streamlined, top‑loading design, providing ventilation and ease of access to the main compartment. The lightweight body reduces carry weight without compromising durability, and the expandable capacity gives flexibility for variable trip lengths. Ergonomic shoulder straps and an adjustable hipbelt improve load transfer and comfort, while external attachment points allow carrying trekking poles and additional gear.

How to use

Load heavier items close to your back and near the hipbelt, with lighter items higher in the main compartment to maintain balance. Use the expandable collar or compression straps to stabilise the load and reduce shifting while moving. Adjust the shoulder straps, sternum strap and hipbelt so the hipbelt carries most of the pack weight; fine‑tune the torso length if available for a close, comfortable fit. Use external attachment points for trekking poles, ice axe or helmet to keep the interior organised.

Recommendations

For extended hikes, periodically open the air‑circulation channels and ensure clothing and sleeping gear are packed to allow airflow; this helps manage moisture and keeps the back contact area cooler. Regularly check straps and buckles for wear and clean the pack according to the manufacturer's care instructions to extend service life.
