Boasting a heavier, more powerful 12-Gauge BlenderBall, a rounded base, and a massive 45-ounce capacity, the BlenderBottle Pro45 is built to go big. The Pro45's massive 45-ounce capacity fits virtually all mass gainer shakes, multiple scoops of a recovery drink, or enough water to keep you hydrated with minimal refills. Easily accommodate oversized scoops and clean the bottle with ease thanks to the extra-wide opening. The rounded base on the Pro45 allows the BlenderBall to mix every last bit of powder and its adjustable carry loop is surprisingly handy, freeing up your hands for keys, your phone, etc. Whether it's protein, a mass gainer, or just plain water, you can rest assured that you've got a tight seal. Like all BlenderBottle brand shaker cups, the Pro45 is proudly made using high quality, BPA- and Phthalate-free materials.

Dishwasher safe, BPA and phthalate-free. Perfect for the thickest protein shakes, smoothies, pancake batter, and more. Adjustable carry loop for added portability and SpoutGuard protects spout from dirty gym fingers. 50% heavier than the standard Blenderball, the 12-Gauge powers through thicker, higher-volume shakes. 45-ounce capacity (Note: measurements only go to 34 ounces).
