For the back he has two padded braces that run next to the spine and relieve them so. To relieve also the abdominal belt is ideally suited, which ensures that the weight of the backpack is not only on the shoulders. The shoulder straps are also padded soft.
The outer mesh pockets suitable for a maximum of 1 liter bottles! The running of the frontside rubber band we used to transport even a towel or a ball.
There is a small pocket on the outside, which I always use for mobile phone, handkerchiefs and purses. Inside at the top is another bag that closes with a zipper. As for me, such as hair bands, painkillers, plasters come in etc. Inside a small portion is removed (from the upper third of the back surface up to down) nor over the entire back surface with material from the rest of the backpack. Top reinforced with lightweight elastic. Here you can store eg sunscreen or the like separately from the rest of your bags.
The backpack is well made and will accompany me certainly a few more years on my trips! I am so far very pleased with my purchase!
