Fill it with ice water at lunch and it's still cold when you train after work. Shake two scoops of protein in it and the last mouthful is as smooth as the first. That's the whole point of this bottle: vacuum insulated stainless steel with a proper mixing setup inside.

We went with steel because plastic has a memory. A plastic shaker hangs onto every shake you've ever made in it, and washing only gets you so far. Steel holds nothing. Rinse this one out and tomorrow it smells like a clean glass.

Mixing happens twice. The removable shaker insert breaks powder apart while you shake, and the cyclonic mix lid spins it again on the way out. Thick powders come out smooth, with no paste waiting at the bottom of the last sip.

The no-spill lid seals shut properly, so it can ride in a gym bag next to your gear without incident. And the vacuum wall works in both directions: cold drinks stay cold for hours, and it holds a hot coffee on a 5am start just as well.

We laser etched the logo instead of printing it. Print sits on top of the steel and eventually peels. An etching is cut into the surface, so it can't flake in the wash or fade in your hand.
