The 0.8L version is enough for me personally for a day trip or a sports unit, for children I would - choose the 0.6L version - also because of the then higher total weight. The shutter stays tight and is only annoying if you are not second degree hand free, it would then have to choose to purchase the separate essay, I could not inspect the original, however. That I chose blue camouflage design is smooth on the outside and remains hopefully less prone to scratches than the versions with the rough coating (which I also have not seen in the original); so far it has certainly gotten no quirks. Pointing out that one should pour any hot beverage I understand so that there is just no insulation and one would risk to burn your fingers when you subsequently touches the bottle and not as an alternative grabs the lid and stored directly. Anyway leads the housing, the temperature directly on, whether hot or cold. The first mission took place in my place in the snow while cross-country skiing and the water therein was correspondingly cold. My 9-year-old daughter came with the bottle and the drinking spout even along well without spills, it has, however, need to keep up with both hands. In the first cleaning, however, I had to pay dearly, because I used the great Can cleaner of Alfi: Available B001F0Q0EY also here at Amazon: among ASIN. He's too big and the bottle has the foam "bristles" tattered. So here's a small number or choose a narrow another model that better fits through the opening that exactly 39mm inside diameter. I would always buy me the bottle again, although it is not cheap in every way ;-)
