I have just as for hiking and for daily route bought the CamelBak for cycling for longer trips, to the university. At first I had some concerns about whether the size unless sufficient, but now they are scattered. In the large compartment comfortably fits a laptop and some documents of daily necessities, such as a drink (if water bladder empty) in the smaller pocket I have all kinds of tools, if I am traveling by bicycle, as a little something to eat , Up front fit comfortably and air shock pump in the smallest pocket. Thus, my good All Round product, which for most trips, whether for work or through the woods, equipped. As a new customer of CamelBak products I'm surprised how robust is the water bubble. Even the drinking cap is much more pleasant to use than the cheaper alternative products. A nice touch are the well-padded lumbar belts and the back cushion "system". Whether the heat is more effectively discharged, the long-term test will yield, but it feels good and stable at.
