This 720 ml bottle is a champion of sustainable design, made from RCS-certified 67% recycled stainless steel and premium Tritan material. It features a versatile dual-function lid with both a sipper and a spout for effortless drinking or pouring. The vacuum insulation keeps drinks hot for 5 hours and cold for 15 hours. Most innovatively, it is packed in a recycled kraft box that can be converted into a desk phone and pen stand, giving the packaging a useful second life.
