Say goodbye to lumpy protein shakes. Our powerful mixing system uses the BlenderBall® wire whisk—found only in Blender Bottle® brand shakers—to deliver smooth protein and nutrition shakes with ease. Forgot to add liquid first? No sweat. The rounded base allows the BlenderBall® whisk to mix every last bit of powder. 

A flexible, ergonomic carry loop provides a comfortable hold for easy portability. Or use the loop to secure keys or attach the bottle to a gym bag.

The double-wall vacuum-insulated bottle keeps drinks icy cold for up to 24 hours, with zero condensation on the bottle.

Guarantee & Warranty

Blender Bottle® products are built to last. At Blender Bottle, we take pride in the quality and design of our products and back each of them with a Limited Lifetime Guarantee. If you experience issues with the material or workmanship of your BlenderBottle® product, we will gladly replace part or all of it, at our discretion—free of charge, with proof of purchase.

As part of our Limited Lifetime Guarantee, we offer a “Leak Proof Guarantee” that covers a replacement Blender Bottle® product of the same style and size—including shipping—if we determine that your BlenderBottle® product is defective and leaks during normal use. While we take great care to ensure that our seals are “virtually leak proof,” we are unable to truly guarantee that a product will never leak. Leaking that results from damage or improper use or care is not covered under this guarantee.
