A spacious, 15-liter running backpack with several zip pockets and an ergonomic cut for several hours of running in the mountains.

• If you are looking for a treadmill vest for long runs or races that are approaching 15 or more hours, then this historically 3rd treadmill vest from the Compressport is one you can always rely on. With its three zip pockets and a volume of 12 + 3 liters, this ultra-stable running backpack will provide you with enough space for nutrition and equipment for long adventures and ultramarathons.

On the front side are two easily accessible mesh pockets, which are designed especially for soft bottles. Above the pockets are fixing loops. On the right shoulder is a smaller zip pocket, which is ideal for keys. The net pocket on the left shoulder is great for storing food packaging. You can easily store gloves, a headband or other energy accessories in the front, bottom, larger pockets. In addition, there is another zip pocket on the left side, which is suitable for storing a mobile phone.

• On the back is the last zip pocket, which holds mandatory necessities that you do not pull out very often. These can be documents, money or thermal insulation foils. This zip pocket covers the largest pocket of the whole vest, with velcro at its top for attaching the camelbak. In the lower half there is an opening for the straw. The pockets on the back are elastic, so they can easily fit the mandatory clothes and equipment. In addition, on the outside of the backpack there is a rubber system in the letter "Z", in which you can store a jacket or raincoat. You can find two opposite pockets in the lower back. Rubber eyelets with internal silicone print are available in case you need to put away your poles.

The vest is maximally breathable and ergonomic with soft seams for unrivaled comfort which is also improved by the new padding on the front that prevents abrasion on the chest. Adjustable side straps can be pulled down very quickly for greater fixation during technical runs. The increase in breathability on steep climbs is possible with the so-called Zip-block. That means that if you leave the zipper clip turned down, the slider will stay in the same position.

• The running backpack has a number of reflective elements on its surface. Not only do these elements increase your safety, but they also allow you to find individual pockets very quickly in the dark.

The Ultrun S Pack Evo 15 has been developed and tested in a trail environment by runners of all abilities. It is designed to bring maximum functionality and unrivaled comfort to achieve the highest personal goals.
