Questions about Fjell Thermo Bottle 750

No. Hand wash only with warm water and mild soap. The vacuum seal between the two steel walls can degrade under dishwasher heat cycles above 60 °C, which would reduce insulation performance over time.

No. At 7.8 cm diameter, it is too wide for most bike cages, which are sized for 7.3 cm or narrower bottles. It is designed for backpack side pockets and hand carry.

Not recommended. The flip lid is not rated for pressure build-up from carbonation, which can cause leaking or lid failure during transport.
