BlenderBottle® Stainless Steel Shaker – Matte Black

Took this to the gym and back and my protein coffee was still cold hours later, which honestly surprised me. The lid locks down tight enough that I've tossed it in my bag without worrying about leaks.

The stainless steel really does keep my protein coffee cold through a whole morning at my desk, no ice turning it watery. The lid locks tight enough that I've tossed it in my bag without a single leak.

Took this on a camping trip and my protein shake was still cold the next morning. The lid locks down tight too, no leaks rattling around in my pack.
