Started with the plastic v1 and v2 caps which were very good, bit did have at least one of those start cracking with soda in it, hence the switch to steel. The 3rd generstion cap is a great improvement with the integrated carrying ring. Only leak on rare occasions if there is liquid in the closure ring when screwing the cap on. Fit wel in cup holders in cars. For me these bottles are the perfect drinking bottles. Have the 350-400 and 500-600 ml single or double walled (thermos) versions.

Perfect voor in de gym!

Acero inoxidable con buen cierre para que no se le caiga al niño. Acero inoxidable por dentro y mantiene bien la temperatura

Le verrouillage et l'étanchéité sont parfaite.

Die trinkflasche ist gut. Was mich stört ist das die Feder nicht so gut federt und der Deckel nicht aufschnappt. Bei kohlensäure hält die Flasche leider nicht dicht.

Good size bottle for a little child unfortunately it started to leak after just 2weeks of use so it’s no use now.
