Superlight - the Sister thereto is the plastic closure!

This bottle is fascinating. It is very stable and yet so light that the focus at all seriousness empty bottle is above the plastic closure - and is already not that difficult. Why I give only 4 stars is the function of the drinking closure. That is indeed massive and strong, but unfortunately you can, if you are not careful, become pinched lip. This is the case if you do not completely pull him out but still drinks. Since the valves for pressure compensation not open far enough, the shutter moves by the resulting vacuum back into the bottle. Ouch. Certainly not happen often, but happens. Furthermore, the valves the drink tend to equalize the pressure to sometimes "Verblubbern", in other words, the air pressure equalization ensures bubbles in the drink. But that only happens when you drink quickly or the bottle has not tilted far enough. The color has surprised me. But already very "neon", slightly ridged coating - for better grip I suppose. Like and above all falls on!

Summary:

Well, I think:
++ Weight
++ Absolutely tight closure
+ Rotatable, and thus "lockable" drinking extract
+ Massive, stable production
+ Items reordered
+ Bright color signal as a coating

Not so good I find
- Extending closure may cause jamming
- Drinking spout / fresh air supply only of medium size
- While drinking sometimes blistering

All in all a great bottle for athletes with small - verschmerzbaren - disadvantages on drinking cap.
