Rally 蛋白搖搖杯

The contoured shape makes it so much easier to grip one-handed while I'm rushing to the gym, and the twist-on handle loop is perfect for carrying with my bag. No leaks at all so far, even after tossing it in my gym bag.

Finally a shaker that actually stays sealed in my gym bag. The contoured grip makes it easy to shake one-handed while I'm walking between sets.

The pop-open spout is super convenient when I’m driving, and the handle loop makes it easy to hook onto my gym bag. Only gripe is the lid takes a firm twist to seal tight, but once it’s on, not a single drop leaks.
