Conveniently, close .... with small defects

Positives:
+ Closure is reliably sealed, material is good and makes a durable impression.
+ The "shell" around the drinking tube prevents fairly well the "lukewarm dishwater" effect at the first swallow from the hose
+ No odor / taste

Negatives:
- The drinking tube is minimal too short for me. 5-10cm more would be fine!
- The cap on the mouthpiece is a good approach, but sometimes sits too loose.
- The drinking cap is very good seal, but the "Operation" (Pinöpel with teeth impressions) is used to

The bottom line:
Good hydration, price / performance fit.
