خلاط بروتين رالي

I've had this for two weeks now and the double wall insulation actually works—my coffee was still warm after a three-hour hike. The pop-open spout is handy when I'm driving, and I haven't had a single leak in my bag yet.

The twist-on lid with the handle loop is a game-changer for me—I clip it to my gym bag and it never leaks, even when tossed around. My coffee stayed hot for a solid three hours during my morning commute, which is way better than my old shaker. The pop-open spout makes sipping mid-workout effortless.

Took this to the gym with iced water and it was still cold hours later. The twist-on lid feels really secure, no leaks in my bag at all.
