Whether at school, in the office or during sports - the versatile bamboo bottles help you to live more environmentally friendly and to drink enough on the go. Thanks to robust borosilicate glass, the water bottles are a sustainable alternative to conventional plastic bottles. At the same time, the drinking bottles are particularly resistant to heat and cold and are also protected from impacts with the removable, lightly insulating cover. The screw cap made of bamboo with a sealing ring ensures that nothing can leak. Note: While the glass bottle is dishwasher safe, the lid should only be cleaned by hand. The neoprene cover can be washed by hand or in the washing machine. When filling with carbonated drinks, make sure to fill the bottle only three-quarters full.
