The Ello Cooper is an 18 oz stainless steel bottle designed with features specific to children's needs. It is built using an 18/8 stainless steel chassis and includes a protective silicone boot at the base. This boot helps reduce the noise of placing the bottle on hard surfaces and provides an extra layer of protection against dents during daily use at school or home.
A key practical feature is the Guardian spout technology, which uses an antimicrobial material on the drinking surface. The lid is an impact-resistant, locking flip-top design that helps keep the silicone spout clean and prevents accidental leaks when the bottle is in a bag. The exterior has a powder-coat finish to increase grip for smaller hands.
- The silicone boot provides stability and helps protect the vacuum seal from impacts.
- Constructed with BPA/BPS-free materials to meet household safety standards.
- The locking lid provides a mechanical way to ensure the bottle stays closed during transit.
To maintain consistent suction, ensure the internal straw is fully seated into the gasket after each cleaning. While the bottle is built for durability, the multi-part lid should be cleaned regularly with a small brush to reach the crevices in the hinge. The 0.8 lb empty weight is slightly heavier than plastic alternatives but offers the benefit of zero metallic leaching and better temperature regulation.
For a larger bottle that also features a straw but with a fun character design, the Zak Designs 27oz Spider-Man Bottle is a great next step up.
