SIGG Alpine Star 1.0 L is built for the outdoors—hikes, cabin weekends, fishing days and hunting breaks. The vacuum-insulated, copper-coated double wall keeps drinks hot for up to 25 hours and cold for up to 105 hours. A silicone base adds grip on wet or icy surfaces, and the ergonomic body with anti-slip zones sits securely in the hand, even with gloves. The Twist&Pour cap opens with a gentle twist so you can pour straight into the included cup. The bottle is 100% leakproof and also works with carbonated drinks. Alpine Star is designed to last. The body uses 90% recycled (post-consumer) stainless steel and the model is about 30% lighter than many bottles of the same volume—easy to carry from day hikes to overnighters. Materials are BPA-free and taste-neutral. Care is straightforward: hand washing extends service life and keeps insulation performance at its best. Key features: long heat/cold retention (25 h / 105 h), 1.0 L capacity, 18/8 stainless steel, copper-coated vacuum construction, silicone base, anti-slip grip zones, Twist&Pour cap + integrated cup, 100% leakproof, suitable for carbonated drinks, BPA-free, hand wash, designed in Switzerland.
