Radian® Insulated Stainless Steel

Exceptionally well built, lightweight with great fit and finish. Loop functionality feels effortless whether drinking or carrying and top is well designed for filling and drinking while minimizing leaks and spills - love it.

Love it to mix up a protein drink to sip on all day. Stays cold through my work day and even into the evening when I don't finish it at work

Its awesome! Functional, good size, great price
