Heavy loads: 15 kg+ / 75 litres+

For heavier loads, you need a back system that provides stiffness and stability, so the weight doesn’t shift as you move. Your body uses a lot of energy compensating for a load that moves around. At the same time, it shouldn’t be so rigid that it restricts natural movement.

Look for a backpack that balances stability with freedom of movement. You’ll also need supportive shoulder straps and a solid hip belt to distribute weight across shoulders, back and hips.

A good technical pack lets you adjust the carry system on the move, allowing you to vary where the load sits.

A backpack for heavy loads (15 kg+) should offer a stable carry system that distributes weight efficiently across shoulders, back and hips.

Key features:
• Robust carry system for heavy loads
• Durable materials
• Multiple attachment points
• Good adjustment options

Medium loads: 8–15 kg / 20–70 litres

In this range, you need good support and stability without unnecessary weight or rigidity. The load is high enough to require close, controlled carry, but not so heavy that you need the most rugged systems. Balance is key. The pack should stabilise the load while still moving naturally with your body. Too much stiffness can feel restrictive, while too little support reduces comfort over time.

There’s wide variation here. Lighter packs (around 8 kg load) may have simpler systems and lower weight, while packs closer to 15 kg typically offer more structure, padding and adjustment. Look for a backpack that provides good load control, comfortable shoulder straps and a hip belt that transfers weight effectively to the hips, while remaining light and flexible.

A backpack for medium loads (8–15 kg) should offer support and stability while maintaining freedom of movement.

Key features:
• Good load capacity with low pack weight
• Adjustable carry system
• Multiple compartments and attachment points
• Hip belt that relieves the shoulders

Light loads: 1–8 kg / 5–20 litres

With lighter loads, the need for an advanced carry system is lower. Focus instead on low weight and functionality suited to your activity. A close, stable fit that moves naturally with your body is still important.

This category ranges from minimalist packs to more organised everyday options. Many are designed for specific activities such as running, cycling or skiing, while others suit work and leisure. At the lighter end, features like hydration compatibility, ventilated back panels or laptop compartments may be more important than carrying capacity.

A backpack for light loads (1–8 kg) should be lightweight, close-fitting and designed for the activity rather than advanced load systems.

Key features:
• Practical pockets for small items
• Ventilated back panels
• Versatile design
