First impression
Orange! The colour really can't be overlooked and dominates the first impression. It is also noticeable that the backpack has many different compartments and pockets. Recently, the trend has been towards simpler backpacks with a main compartment, a security compartment and perhaps another compartment for small items. The Dimension Backpack has much more to offer. There are:
Main compartment
Goggle compartment
Key compartment (or for similar small items)
Special compartment in the main compartment (according to the manufacturer for the first aid pack)
Compartment for shovel and probe made of extra durable material
Detached front pocket with holes for wet skins (the holes are intended to ensure that the moisture can escape)
Also, of course, the compartment containing the airbag balloon, that the wetness can escape)
In addition, of course, the compartment in which the airbag balloon is located. You don't normally have to reach it and I only found the charging cable for the rucksack hidden here after the first test deployment.
Otherwise, the backpack has the usual backpack features. According to the manufacturer's website, there is a carabiner on the shoulder strap to which you can attach a water bottle. I wouldn't have noticed it, but I don't miss it either. The height of the airbag deployment handle can be adjusted with a bit of tinkering. The drive for the airbag system is positioned in a neoprene cover in the main compartment. You have to open the cover (zip) to install the batteries, plug in the charging cable and operate the on/off lever. A mesh window with zip allows you to check from the outside: if a small light occasionally flashes green, the backpack is on. With a total weight of 3150g (manufacturer's specification), the rucksack is rather heavy compared to models of a similar size from other brands. The airbag system without the backpack weighs 1140g.
