Choosing a backpack with a high-quality and sophisticated back system is the alpha and omega of a successful trek. The Lowe Alpine brand has earned its place in the outdoor world, focusing on the innovation of backpack backs.
The technology, material, and style of the back system determine how the backpack will carry throughout your travels. It determines load capacity, ventilation, and comfort. That is why choosing a backpack or hiking backpack, along with choosing quality hiking boots, is a truly essential item on your travel to-do list.
Lowe Alpine offers a total of 7 back systems:

The back system allows for the extension of the lower part by up to 5 cm.
