The Alpine Star is designed for extreme conditions and offers reliable performance for all outdoor activities. With its copper-coated double-wall insulation, it keeps drinks warm for up to 25 hours and cold for up to 105 hours. The robust construction is lightweight and durable, making the bottle suitable for use in icy heights or rough terrain. A non-slip silicone base ensures a secure footing even on slippery or wet surfaces. Anti-slip surfaces and distinctive grooves improve grip, even when wearing gloves. The Twist&Pour closure allows easy pouring directly into the integrated drinking cup. This combination of well thought-out functionality and high insulation performance makes the Alpine Star a reliable companion for any expedition.
