The bottle actually looks as nice as in the pictures. Your entire capacity is 500ml Although, the graduations on the side walk but only up to 400ml. In still water the shutter keeps you tight and the bottle can be readily transported in a backpack. Unfortunately, I did not like the opening. While that is great, so that you can clean the bottle well, but when I came to drink with his nose always to the brink. I thought that was not as nice and was looking for a suitable drinking closure. This drinking closures there but apparently only for bottles with a wider opening.
Therefore, I have now bought myself a Nalgene Everyday OTG and a humangear bottle cap. The greater capacity of Everyday Otg appears practical and the drinking closure of humangear also holds tight in calm water but you can also still good drink.
The 500ml version I have passed on to my girlfriend, which she uses as a water bottle at the gym. Larger nose but less trouble drinking - There's stuff!
