This is my first race backpack, and I have to say I like it better than me. I have the part actually bought, so I can take the bread for the family in the morning jogging bem equal. For as a normal backpack I was definitely too big and too heavy. And for the purpose of the backpack is ideal, it go in 8 normal bun :-) The only shortcoming: the upper chest strap is almost a bit small. For me, he is now set almost to maximum length, I could imagine that man as I already get with a wider chest as difficulties. For me it is enough, however, even with track jacket.
