BlenderBottle® Stainless Steel Shaker – Cobalt Blue

Filled it with iced coffee at 7am and there was still ice clinking around at lunch. The lid locks down tight too, no leaks rolling around in my gym bag.

Took this on a camping trip and my iced protein coffee was still cold the next morning. The lid locks down tight enough that I tossed it in a backpack without worrying about leaks.

The stainless steel walls genuinely keep my shake cold from the gym through my whole morning commute. That little wire whisk ball breaks up protein powder clumps way better than I expected, and the lid hasn't leaked once in my bag.
