Mix protein, coffee, or pre-workout smoothly every time with this food-grade 304 stainless steel shaker bottle. Unlike plastic shakers that absorb odors and stain over time, stainless steel resists corrosion, keeps drinks cold for hours, and stands up to daily gym bag abuse without cracking or leaking. The wide mouth makes it easy to add powder and ice, while the secure, leak-proof lid means you can toss it in your bag without worry. Available in two sizes to match your hydration needs, whether you're headed to a quick lift or an all-day event.
