Running Bag 331 - 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.

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.

Our backpack's Outstretch™ technology ensures that the items stored in the pockets - whether empty or full - fit tightly and do not wobble back and forth. This technology also ensures that the backpack expands outwards when filled, which ensures optimal comfort regardless of the load. Thanks to a combination of materials where stretch and modulus of elasticity have been carefully calculated, as well as the use of bellows, Outstretch™ technology allows the bags to adapt to the shape of the contents and compensate for the inertia effect when running.

With a handle accessible from the front of the backpack, this tunnel bag is ideal for storing your rain jacket while keeping it within easy reach. Thanks to the generous bellows and the elastic closure, you can safely store up to two jackets.

The ergo strips strategically placed on the runner's shoulder ensure that the quiver holder stays firmly in place, while the middle loop accommodates the quiver holder's fastening system. Whether positioned vertically or at an angle – your quiver holder is always at the right height and the fastening system for the sticks is very easy to access.

Located in the shoulder strap mobility range, this backpack is characterized by ending halfway back, allowing contents to remain easily accessible even while running. It comfortably offers space for additional running accessories: headlamp, cap, sweatband, glasses, food or jacket. Thanks to its elastic edging in combination with the bellows, it adapts to the size of the stored items and at the same time ensures that they are securely held.

This is the only pocket that is not accessible during the run; It is therefore intended for safety purposes and cannot be used during the race (e.g. for a change of clothes).

Thanks to its reverse cross opening and elastic material, this small, secure bag can hold keys or a credit card. The high elasticity of the material allows the bag to conform to the shape of the items, while the high elastic rigidity presses the contents firmly against the bag's framework to prevent wobbling back and forth.
