I have for my USA - sought leave a backpack, in my laptop fits, so I can make this easy, without an additional bag to carry, take on the plane. This purpose has been met in full and there it is super comfortable to wear and matching bottle size also on the outside space for two bottles, he finally was a constant companion of our walks. He has survived the hardships so that he will accompany me to the next and probable many more vacations.
The notes with the passage for headphones I can add: There are on the side a zipper on a bag to the results of the passage and in the course you can put even the mobile phone / MP3 player (I have added but only Late detection).
