Advantages

Chest strap
The adjustable chest strap helps to stabilise the entire structure. Thanks to it, the backpack does not shift or compromise balance, which translates into the user[s safety during mountain activities.
Adjustable
Adjustable braces and straps ensure even weight distribution. The backpack will not shift or upset your balance. The carry system has a wide range of adjustment, you can easily adjust it to your body shape.
Compatible with hydration system
The backpack is compatible with a hydration system. This gives you easy access to your drink during climbing or other prolonged outdoor activities. You don[t need to take off the backpack for this purpose.
Comfortable use
Adequate capacity, a customised carrying system and the materials used are just some of the features of a climbing rucksack that enhance comfort. This model will be comfortable in any situation.
Compression straps
They are used to adjust the size of the backpack for the amount of equipment and accessories carried in it. They can be widened as required for more items and tightened accordingly for less, thus increasing the comfort of the rucksack.
Hip belt
The hip belt will help distribute the weight. It relieves strain on the shoulders and back and is ideal for long hikes and climbing with a heavy rucksack. It ensures that you do not feel excessive weight on your shoulders, but that it is distributed evenly.
Hook for an axe
The chequer clip is a solution that guarantees the user[s safety. In the event of a fall, it protects against injury. A practical aspect - the equipment you need is always within reach.
DWR
The DWR coating makes the fabric water repellent, so that water forms droplets on its surface and runs off instead of soaking in. This protects the fabric from getting wet quickly, providing greater comfort in wet conditions, but does not guarantee full water repellency.
YKK®
Designation of the reliable zippers of the Japanese brand YKK®, used in high-end sportswear and accessories.
