In summer, its content remains cold, warm in winter. The mouthpiece has no equal. At outdoor temperatures around 5 degrees is hot is filled tea leaves after 2 hours still pleasant to drink, at -5 degrees he is after an hour still warm to drink. In my tours at 30-33 degrees she held my drink long cool. The drinking valve is 100% tight. Pressing the bottle while drinking the flow / fluid intake can dispense well. It does not have to be "sucked" on the bottle.
My conclusion: My best bottle that is well worth the money. We recommend!!
