I got me a long look around the market in the area and I was very difficult to decide between the 12, 5, and 1.5 liter models. Finally, I am for the 5 liters of Salomon decided, since I was hoping so to get the compromise between lightness and capacity - I was not disappointed.
I use the backpack for tours from 2 hours up to 6 hours.
It was important that the backpack is big enough for a windbreaker, a rain jacket and a change of shirt.
Furthermore, should headlamp, mobile phone, mp3 player, bars and gels can be stowed within reach and safely.
Compatibility for hydration system and a way to carry walking sticks were also desirable.
The Salomon SLab 5 comes with two high-quality bottles of 0.5 liters instead of a bladder, for which it is compatible, however, and it specially mitliefert a Isoliereinschub. In principle, a matter of taste - but I am excited about the bottle - who does not yet know, have to try! Who can do without the bladder, then it in your backpack "ample" space. It is positive that the material can stretch well, yet everything holds together beautifully. Well I also like the division of the storage space with two separate areas and an extra pocket for Bundled Isodecke. At the bottom of the backpack, two found left and right through zipper lockable compartments for valuables / phone / etc. and two open pockets for gels / bars / lamp etc.
The chest straps are very comfortable and offer not only the bottle, additional pockets for small items that included whistle, gels, keys, etc.
I can do without on the bladder, and fill me two bottles of water, if necessary on the route again and again. With hydration backpack in the place is already very tight. My windbreaker had then still space, but my hardshell raincoat would have to stay at home.
Therefore, for me an absolute half-day tours Champion. For full or multi-day trips, or for people who have a higher water consumption of the backpack is definitely minimalist.
