An emblematic creation celebrating 15 years of the Oxsitis brand.

At the heart of this set is the ULTIM 12-liter backpack, featuring some ingenious new features. The new, removable front adjustment system guarantees fast, customized adjustment, while its wider side adjustment improves anatomical fit and stability. 2 running-accessible back pockets are ideal for storing poles, jacket or cap, without having to remove the bag. Water-resistant and durable, it has been designed with a new 4 Way Stretch fabric for enhanced running comfort.

In addition to the bag, the set also includes the SLIMBELT ULTIM. This hydration belt offers greater storage capacity. Made from 100% recycled polyester, its recycled stretch fabric adjusts perfectly to the body. To prevent the belt from moving, even at high speed, anti-slip strips have been added on the inside. The pole holders and magnetic bib holder make this belt ideal for trail running.

To top it all off, the ULTIM COFFRET comes with the soft Endurance Cap. Lightweight and breathable, it wicks away excess perspiration for maximum comfort. An adjustable strap at the back of the cap lets you fine-tune your fit. It folds easily for fast, optimized storage.

This unique set combines quality, functionality and style, while paying tribute to the heritage of the Oxsitis brand.
