What are the differences between the various back systems? (Advanced Easy Trek, VENtury, adVENtury)

They all have infinitely adjustable back systems but the differences are in the finish:

• Advanced Easy Trek system: 3D mesh back panel that the straps run across, thus never coming in contact with your back.
• Easy Trek system: the metal stiffeners are visible and not shielded from your back
• VENtury system: a flat-back system with two foam sections (left and right) due to this, the rucksack shapes itself well to your back and there is good ventilation via the central channel.
• adVENtury system: a rounded plastic frame, causing the rucksack to stand slightly away from your back. This provides very good ventilation/removal of warm air. Moreover, the frame retains its shape regardless of the weight and the rucksack has a rugged, adjustable hip belt
• Air Ventilator system VS: the frame is made of flexible interwoven metal stiffeners and is not as rounded as the adVENtury system
