Ventilated Backpacks Benefits

In this video you will see me using a ventilated backpack while climbing 3000 meters high mountains in the Dolomites, Italy. I describe my experience with Deuter Futura Vario 50 Pack.

Note that there is no editing here, this is just as it was recorded. My video camera obviously did not record the sound properly, and I could not put it on a tripod, sorry for this.
