Voltrx blender bottle has an easy to remove top that includes an easy to open flap and carrying loop. It’s easier to open than others, and the contents won’t spill on you when you open it.
The capacity of the protein bottle is 700 ml, which is certainly large enough for most protein/supplement drinks. The milliliter and fluid ounce sizes are marked on the shaker cup.
Overall, this is a lightweight shaker bottle that mixes perfectly with the drink you want without clumping
