UltrAspire Zygos 5.0

Since the first version of the Zygos, tens of thousands of runners have used this 14-litre high-capacity race waistcoat. The lightweight and comfortable wrap-around design, complemented by the ErgoFit Harness, ensures that the Zygos 5.0 is stable, comfortable and unrestricted. The backpack's adjustable MaxO2 Form closure system secures and adjusts to the weight of the backpack. This innovative system allows the backpack to be adjusted to the body with a single pull. Similar to the MaxO2 Sternum, this system allows the backpack to be secured without hindering natural breathing. The backpack is equipped with 8 pockets, including 2 zipped shoulder pockets, a double 4-way stretch mesh pocket, two stretch mesh pockets (one of which is zipped and suitable for a large mobile phone), a zipped side pocket and a magnetically closable side pocket. The main compartment on the back has been reinforced at the stress points with XT fabric, which contains stronger ripstop fibres than steel. This backpack includes a 2-litre hydration bladder that fits in the removable insulated compartment. Available in 3 sizes to ensure a perfect fit.
