The Santeco Mara is a children's insulated bottle made from 18/8 stainless steel with double-wall vacuum insulation, keeping water cold for up to 24 hours or warm drinks warm for up to 12 hours (maker's figures). It has a flip straw lid that opens with one press and seals itself when closed, with a soft, food-grade silicone straw, plus a second lid with a cup for pouring. A protective silicone boot on the base helps it stand firm on a desk. It comes with its own padded carry bag with an adjustable shoulder strap, so a child can wear it cross-body on a hike or carry it to school. This version has the koala design. The box includes the bottle with flip straw lid, an extra lid set, a straw cleaner, the carry bag and the shoulder strap. Hand wash for the longest life.
