[Double-Wall Insulation Keeps Drinks Cold or Hot for Hours] Whether it's an icy post-workout shake or hot morning coffee, the vacuum-insulated 304 stainless steel body maintains your drink's ideal temperature for 6-12 hours. Enjoy your beverage exactly the way you want it, long after you've left the house or gym. [Threaded Mixer for Consistently Smooth Shakes] No more rattling shaker balls or half-mixed powder chunks. The built-in threaded mixer efficiently breaks up protein and supplements as you shake, delivering an evenly blended drink every time without the metallic clatter of traditional wire balls. [Detachable Bottom Storage – Carry Powder & Liquid Together] The removable base compartment holds your protein powder or supplements separately from the main cup. No extra containers needed—just twist off, pour, and shake for a freshly mixed drink at the gym, on the trail, or at your desk. [Leak-Proof Twist Lock Lid & Permanent Measurement Marks] The precision twist-lock lid with silicone seal prevents spills in your gym bag or car. Inside the 20oz cup, permanent engraved markings clearly show up to 16oz for accurate pre-workout ratios—no guesswork, no sticky mess. [Odor-Free 304 Steel & Ergonomic Carry Handle] Crafted from BPA-Free 304 stainless steel, this shaker won't absorb yesterday's protein smell like plastic bottles do—every drink tastes clean and fresh. The flexible handle and rounded body provide a comfortable, secure grip, while the durable metal construction handles daily wear and outdoor adventures.
