With the practical bottle holder, the drinking bottles are the perfect companion for cycling. The opening is large enough for ice cubes, and the rounded edge allows for comfortable drinking. Made from BPA-free 18/8 stainless steel, they are hygienic and easy to clean - even in the dishwasher - and suitable for any type of beverage. Unlike bottles made of plastic or aluminum, the drinks inside retain their own flavor, and carbonation is preserved. The 24bottles drinking bottles are reusable and recyclable. They have a drinking opening of approximately 3.5 cm. The double-walled Clima Bottle keeps liquids warm for up to 12 hours and cold for up to 24 hours.
