Arc'teryx Alpha FL 20 climbing backpack (X00000898400)

The Arc'teryx Alpha FL 20 Climbing Backpack is the perfect companion for climbing enthusiasts, offering exceptional durability and functionality. Made from materials such as polyamide and polyarylate, the backpack is resistant to mechanical damage and ensures long-lasting use. Its 24-litre capacity makes it spacious enough to hold essential gear while remaining lightweight, weighing just 600 g.

Advanced Arc'teryx Technologies

The Arc'teryx Alpha FL 20 climbing backpack utilises advanced technologies that enhance its functionality and user comfort. Arc’teryx Hadron™ technology provides exceptional material durability, while Arc'teryx AC² supports its waterproof capabilities. Additionally, the use of Arc’teryx Watertight™ technology offers protection against moisture, which is crucial in changing weather conditions. Thanks to RECCO® technology, users can feel safer, with easier localisation in emergency situations.

Materials and Construction

The Arc'teryx Alpha FL 20 climbing backpack is made from Cordura® fabric, providing extra resistance to abrasion. The use of Vectran™ increases its tensile strength, which is important when carrying heavier equipment. Furthermore, the DWR finish enhances moisture resistance, particularly useful in challenging terrain conditions. The hip and chest straps ensure stability and comfort during wear, which is key for even load distribution.

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.
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.
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.
Climbers
The sturdy handles help organise the equipment and necessary accessories carried during climbs and other mountain activities. They allow you to carry more of the things you need during your hikes.
Waterproof
The waterproof climbing rucksack will prove its worth in changing mountain weather. Resistant to rain, snow, it prevents moisture from getting inside. Water does not leak through the seams of the backpack either.
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.
Cordura®
A fabric made of polyamide fibres, coated with a layer of Teflon, renowned for its extraordinary resistance to adverse external factors. The fabric is lightweight, waterproof and very durable. It is used in the manufacture of specialised clothing and footwear, but also backpacks, harnesses and protectors.
Vectran ™
Vectran ™ anti-tear technology is a synthetically produced fibre with tremendous tear strength and very low weight. They do not adversely affect rolling resistance.
RECCO®
A patented safety system for avalanche emergencies. The technology involves placing a transmitter inside clothing or footwear that is compatible with the detector used by rescuers.
Arc’teryx Hadron™
An extremely durable face fabric dedicated to clothing and equipment that are subjected to harsh conditions, such as mountaineering jackets and backpacks. Thanks to its advanced construction, the fabric is incredibly lightweight.
Arc’teryx Watertight™
The technology laminates the zips with a special urethane coating that seals them and protects them from the weather. This solution eliminates the need for protective zipper flaps, thereby reducing the weight of the product.
Arc'teryx AC²
Arc'teryx's AC² (Advanced Composite Construction) technology, characterised by high water resistance and the use of bonded seams, ensures that the contents are protected from the harshest weather conditions.
