Bring your nutrition with you and mix it when you are ready. The Mammoth Fiber Shaker Bottle combines a durable 17 oz BPA-free cup with a detachable bottom compartment that keeps powders and small essentials stored separately until you need them. Use the storage compartment to carry fiber, protein, electrolytes, pre-workout, or other powdered supplements without mixing them into your drink ahead of time. When you are ready, detach the compartment, add the powder to the cup, and use the included shaker ball for a quick, smoother blend. The secure flip lid helps reduce spills during daily use, while the built-in carry loop and included carabiner make it easy to attach the shaker to a gym bag, backpack, or travel gear. Its compact all-in-one design is built for the gym, office, travel, hiking, and everyday routines.
