Orion Tumbler Lid (iLyd)

Maximize the performance of your tumbler! The patent pending iLYD from Southern Line is a revolutionary product that increases the ice retention of your tumbler by 30% and literally DOUBLES the heat retention. Made from BPA Free materials, the iLYD features an industry first (and patent pending) double wall construction as well as a flip top that COMPLETELY seals when shut. Keeping the lid bound to the cup is another industry first, a 4 tier gasket, which ensures your lid stays put even if the tumbler is dropped or tips over.
