BlenderBottle Classic Shaker Bottle Perfect for Protein Shakes and Pre Workout, 28-Ounce (2 Pack), Grey and Black

Everything works great with these, except with the colors of them it makes it impossible to see the lines to know how many ounces of liquid you are getting.

This is deceptive. Maybe it holds 20 oz of fluid, but you cannot mix a 20 oz shake. Can only mix a 16 oz shake. Blender Bottle makes a 20 oz bottle w markings to 16. These are not it! You need 4 oz of space to shake. Don’t be fooled… these are 16 oz blender bottles.

Love the colors, easy to use and works for all work out powders.

I bought this to mix medicine in 8oz of water. Perfect size and doesn’t leak. Really easy to close and open with good grip from the top and bottom. Easy to clean and survived the dishwasher.

Son fabulosos para llevar mi proteína al Gym me gusta todo los comprare nuevamente.

Best blender bottles, perfect for the normal 6-10 oz protein shake. Not ideal for 20 oz drinks which it says it can hold. But that’s not really what I need them for. They look great in black, seal tight, no leaks.

I use a collagen powder in my almond milk and this is a great way to mix it. A blender makes too much noise and always made my mixture foam up. Glad it came in a three pack so I dont have to wash my cup every day.

easy to use and no mess when shaking. dishwasher safe

Seems like all I can find is the big shaker bottles anymore, but I didnt want anything that big.. until I found these. Perfect size for my 8oz of protein shake. Love the little wire mixer balls, they work perfectly! No leaks after weeks of dishwashing; best on the market for the price. I wanted bright colors and these were exactly that; easy to not mistake mine for someone elses in the company fridge! Definitely worth every penny!

I dont know if it leak proof - if you run it in dishwasher it may lose the lid tightness and start leaking
