4 Stream - Mammut Hiking Backsystems

For athletes, a comfortable body temperature is an essential consideration. Sweating is annoying, the energy it requires should be used for more important things. The 4-STREAM system effectively prevents perspiration by providing ventilation from all four sides. The distance from the body at the shoulder area also allows rising hot air to escape upwards. This results in a “chimney” effect.
