| 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. | |

1. Adjustable back length
The 3-step suspension system can be easily adjusted to suit the length of the wearer’s back. 2. Fast packing The traditional curved shape of air space suspension systems has been reduced to a minimum, making it easy to fill and unpack. 3. Steel frame Provides stability for the back, prevents pressure points caused by equipment and distributes the load widely across the back. 4. Vario System A simple manoeuvre while on the move makes this outstandingly ventilated air space suspension system into a full-contact backpack which offers better load control in exposed terrain. 5. 4 STREAM The back is effective ventilated from all 4 sides, the distance from the body at the shoulder area allows rising hot air to escape upwards.

The small contact area helps to stop the body from overheating and thus reduces the energy required for cooling. |
