SiS Shaker Bottle 700ml is designed for preparing protein shakes and recovery powders without needing a separate blender. The 700ml capacity gives room to mix a serving of your preferred SiS product with water and is useful for gym training or post-session nutrition.

A mixing insert helps reduce clumps when shaking, while the integrated drinking spout makes it convenient to drink straight from the bottle. Its portable form works well for regular training routines, whether you prepare recovery drinks at home or after a workout.
