500 ml stainless steel bottle with vacuum insulation | Kalsten

Hot drink cold, cold drink warm – and that just after half an hour on the go.

The coffee is lukewarm, the water is warm, and the smoothie has long lost its temperature – who doesn’t know this after an hour of training or at work? The double-walled vacuum insulation of this stainless steel drinking bottle keeps hot and cold drinks at temperature for up to 24 hours. Simply fill it up, take it with you – and drink whenever it tastes good.

Benefits

• No more lukewarm sips on the go: Thanks to double-walled vacuum insulation, coffee stays hot and water icy cold – even after hours in the backpack or car.
• No more searching for the right holder: The straight cup-shaped body fits into most cup holders in cars, bicycles, and strollers without adjustment.
• No worries about rusting or peeling: Made of sturdy stainless steel inside and out – no plastic taste, no visible wear after weeks of daily use.
