It makes it possible to have everything you need without having a backpack on wich keeps the heat on top of your back.

You can choose to wear it both over or under your sweater.

The large pocket is 2 liters and can contain, for example, tools, a windbreaker or similar.

Inside the pocket there are also partitions and smaller compartments for dividing your things.

In addition, there are two spaces for bottles on the sides of the bag.
