Mighty Bottle is 17 oz / 500 ml and fits nicely in your hand and most cup holders. It's sleek, simple, and stylish— oh and did we mention über functional & leak-proof? Say goodbye to chunks & clumps forever. With smart blending technology, Mighty Bottle turns Mighty Blendz powder and water into a smooth, creamy instantly blended smoothie. Simply snap the mixer net into place and it will hold into place. That's right, no more rattling or loose parts: Mighty Bottle makes way for effortless, silent mixing. The mini carabiner helps to attach the bottle to your bag or backpack for wild adventures. The attached storage compartment (100 ml / 3.5 oz) allows you to bring along your essentials. We love to put our vitamins + supplements in the storage compartment when Mighty Blendz is the first meal of the day. Don't need any storage? Simply screw off the storage compartment for a more compact Mighty Bottle. *BPA and DEHP free
