The 32-ounce Pro Series bottle is designed to provide a larger capacity for those who prefer bigger servings or need more liquid for their protein shakes or pre-workout drinks. It features the same leak-proof seal, secure screw-on lid, and BlenderBall wire whisk for efficient mixing as the other Pro Series bottles. The 32-ounce Pro Series bottle is also made of durable Eastman Tritan plastic and is BPA-free and dishwasher safe.

The 24-ounce Pro Series bottle offers a slightly smaller capacity, which might be suitable for those who prefer smaller portions or find it more convenient to carry around. It has the same features as the larger Pro Series bottle, including the leak-proof seal, secure screw-on lid, and BlenderBall wire whisk.

Both the 32-ounce and 24-ounce Pro Series bottles in Black are great options for mixing protein shakes and pre-workout drinks. The choice between the two sizes depends on personal preference and specific needs, whether you prefer a larger capacity or a more compact and portable option.
