    Product Description

    The Impulse 20 is a versatile companion for demanding day trips. It is ideal for trail runs, bike touring, mountaineering or a hiking trip.

    The large zipper opening makes the main compartment quick and easy to access. Inside, four mesh pockets and one zippered pocket as well as two pockets on the sides offer various organizational options. A hydration system can also be easily stowed in the integrated pocket. Thanks to the central port on the back, the hydration tube can be attached to both the right and left shoulder strap.

    On the outside, a zippered pocket and three elastic mesh pockets provide additional storage space. A removable compression system reduces backpack volume when needed and allows for additional attachment options. Daisy chains and a refined tool blade make it easy to attach ice tools.

    A thermo-molded back pad and padded shoulder straps ensure comfort. A removable padded hip belt provides additional support.
