Hot & Cold One. The bottle made from high-quality stainless steel is vacuum-insulated and keeps drinks hot up to 10 hours or cold up to 18hours! The built-in tea filter is perfect for using tea leaves or fruit slices, and the anti-slip pad protects the bottle from slipping. The drinking lip – which can easily be adjusted for left or right-handed use is made of Tritan: a material that is absolutely tasteless and therefore does not alter the taste of the drinks. Additionally, the clever cap – which can be opened and closed with one hand – reliably keeps the mouthpiece clean. The new Hot & Cold One Light is a perfect alternative to disposable bottles and coffee mugs!
