The Dual Shaker 2.0 is one handy little tumbler for on-the-go convenience. Designed specially for sports and fitness enthusiasts, it allows you to conveniently store your protein powder and liquids in separate chambers before heading out. When it's time to drink up, just shake the bottle to combine the contents of both chambers. That way, you get to enjoy a freshly-prepared protein shake anytime you want. Another plus point? There's a little compartment for you to store your health supplements as well.
