Running Bag 555 - Black

This patented technology allows you to quickly remove the water bottle from the outside of the bag and put it back in, even if the front pockets are wet or full. The bottle neck locks itself onto the top opening of the bag to ensure optimal grip. The bi-stretch material (maximum stretch of 65%) and the tensioned silicone elastic band ensure the perfect balance between stability and easy access.

This patented technology, where the bag is tilted relative to the flange, reduces the feeling of swaying by four times. By tilting the bag by 17°, we increase the contact surface of the bag on the flange: not only the lower part, but also the side supports the flange. The load (force divided by the contact surface) that the weight of the bottles exerts on the pockets and thus on the structure of the backpack is thereby reduced by two thirds. A finite element model shows that the displacement of the bottle upon impact - and thus the feeling of swaying - is reduced fourfold.

The structure of this backpack ensures an anatomically tailored fit that adapts perfectly to the shape of the runner's body while ensuring incredible stability even at high speeds and with a fully loaded backpack. For this purpose, together with our partner Taiana, we have developed an innovative and exclusive material that is completely rigid vertically but has extreme elasticity horizontally. Thus, this framework provides a rigid support to which the bags are attached and limits the inertial effects of the swinging movements during running, while at the same time allowing maximum and unrestricted freedom of movement of the chest thanks to its low horizontal elasticity.

This elastic cord at the top of the hip flask pocket provides additional support to the neck of the bottle, even when the bottle is empty.

The two large wings of the backpack not only ensure stability, but can also serve as additional pockets when heavily loaded. Made from bi-elastic warp and weft fabric, these wings naturally press the contents against your back: so you can easily carry two additional water bottles or a jacket without them sloshing back and forth. The high elasticity of the material (maximum stretch of 79%) ensures considerable capacity, while the Cordura threads guarantee outstanding durability.

Our self-locking zipper ensures optimal and even closure of the backpack while maximizing the volume of the front pockets. The self-locking system allows the backpack to be opened partially and precisely, especially on climbs when there is less need to strap the backpack and better ventilation is important. It is complemented by a clip with which the zipper can be fully opened - practical for keeping the backpack comfortably in place on long climbs and at the same time being able to set off again without worry if the gradient eases for a few meters.

This large pocket allows you to maximize the capacity at the front of the pack, so all your food and running supplies are easily accessible and won't wobble around - even when you're extremely tired or less alert. Thanks to its material, this bag has an exceptional maximum stretch of 80%, allowing it to almost double its volume and facilitate access to the contents through visual control. Their high elastic stiffness (apparent modulus of elasticity of 0.125 N/%) also ensures that the stored items fit tightly and stay in place.

This 50ml bag allows you to safely store your keys or headphones without them slipping around. This bag's reverse cross closure combined with the bi-stretch material allows for intuitive access to the contents. The bag's high elasticity with a maximum stretch of 80% ensures a perfect fit to the items being transported, while its elastic rigidity (apparent elastic modulus of 0.125 N/%) ensures support and stability.

This safety whistle complies with the equipment regulations of the largest ultra trail runs.

In this zippered pocket on the front you can store your cell phone, keys or food safely and without wobbling. This bag made of bi-elastic warp and weft fabric not only increases the capacity in the front area, but also ensures perfect stability of the contents. Their high elasticity (maximum stretch of 80%) and their high elastic rigidity press the objects tightly to the structure of the bag and limit the inertial effects when running.

This patented technology consists of a system of upper and lower criss-crossing slats that prevent swaying while running, even under extreme loads. The rigid upper slats provide the support needed to limit inertia while running, while the elastic lower slats hold the load firmly against the runner's back. The load of the backpack is pressed against the runner's center of gravity and remains firmly attached to it. Backpack and runner form a unit: there are no asynchronous oscillations between the two systems. It should be noted that the lower slats can also increase the load capacity when heavily loaded.

This patented back bag has multiple compartments, each attached to the backpack construction, allowing the equipment to be carried to be divided. This compartment system not only ensures clarity when storing, but also distributes the weight of the contents evenly and reduces freedom of movement of the contents. Inspired by the design of tank trucks, this technology distributes weight evenly across each compartment, maximizing the carrying capacity of the backpack construction. The local loads caused by the weight of the load are therefore lower and the inertia effects caused by vibrations of the backpack during running are significantly reduced.

This waterproof bag made from EvenSafe 3L™ material is located inside the large backpack and is ideal for safely transporting your personal items such as bank cards, passports and chargers. Because it is sewn directly to the rigid structure of the backpack, this bag remains very stable even when heavily loaded. The waterproof material protects your items from moisture.
