The advantages of a 40-litre capacity

A 40-litre capacity offers extended volume, enabling you to carry more gear than a mid-sized pack. This storage volume promotes organised packing thanks to a spacious main compartment complemented by secondary pockets and external attachment points.

This level of capacity allows you to pack:

  • additional layers
  • extra equipment
  • larger water or food reserves
  • technical accessories secured to the outside of the pack

Organisation and carrying comfort of a 40-litre pack

A 40L trekking backpack enables you to carry a moderate load in a stable and balanced way. The carrying systems feature structured back panels, ergonomic shoulder straps, and supportive hip belts to distribute the weight evenly between shoulders and hips.

The design of the carrying system is crucial. Most models include:

  • a structured hip belt
  • ergonomic shoulder straps
  • a reinforced or ventilated back panel
  • side compression straps
  • attachment points for external gear

An even distribution of the pack’s weight between shoulders and hips helps maintain load stability while ensuring comfortable carrying over long distances.

FAQ

How many kilos can a 40-litre backpack carry?

For trekking, a 40-litre backpack generally measures between 55 and 65 cm in height, 28 to 32 cm in width, and 20 to 25 cm in depth. The most common size is around 60 × 30 × 22 cm. Dimensions may vary slightly depending on the design and carrying system.
