Description
Best for: A light everyday shaker. No ball to lose, top-rack dishwasher safe, and it fits most cup holders.
Lumpy protein is a solved problem. GRYNDWEAR's 600ml protein shaker bottle uses a moulded vortex base that spins powder through the water as you shake, breaking clumps without a wire ball rattling around the shaker cup. Fewer moving parts means less to lose, less to clean and no metallic taste in your first mouthful after a heavy set.
The body is Tritan, a clear, impact-resistant copolyester that stays odour-neutral and does not cloud or crack the way cheap plastics do after a few months as your everyday gym shaker bottle. It is BPA-free, dishwasher-safe on the top rack and wide enough at the mouth to take a full scoop, ice cubes or a bottle brush. Moulded volume markings run up the side so this protein mixer bottle helps you hit a mix ratio without guessing.
The screw lid seats on a gasket and the flip cap clicks shut, so it rides upright in a bag without leaking over your kit. At 600ml it holds a standard two-scoop shake with room to shake properly, and the tapered profile drops into a bottle cage or a cup holder. Rinse it straight after use, because that is the only real trick to a shaker that never smells. It is a small habit that keeps a shaker usable for years rather than months, and saves you buying another one.

No Lumps, No Rattling Ball
The moulded vortex base spins powder through the water as you shake, so clumps break up on the way through instead of collecting at the bottom. Fewer moving parts means less to clean, nothing to lose in a gym bag and no metal taste in your first mouthful after a heavy set.
Fill the water first, add the powder second, and ten seconds of shaking is enough for a clean mix.
Protein, pre workout, creatine and electrolytes all mix the same way, and it handles thicker blends like a mass gainer too.
Why GRYNDWEAR

Frequently Asked Questions
Does it really mix without a ball?
Yes. The vortex shape in the base spins the liquid as you shake and breaks clumps on the way through, so you get a smooth shake with nothing rattling inside.
Is it BPA free?
Yes. The body is Tritan, a clear copolyester that is BPA free, odour neutral and impact resistant.
How much does it hold?
600ml, with moulded markings up the side so you can measure water and liquids without a separate cup.
Can I put it in the dishwasher?
Yes, on the top rack. The wide mouth also takes a bottle brush if you would rather wash it by hand.
Will it leak in my bag?
The lid seals firmly and the spout closes over the top, so it holds up to being tossed in a gym bag between sessions.
