I was pleasantly surprised by how sturdy the twist-on lid feels—no leaks in my gym bag so far. The handle loop makes it easy to carry during my walk to work, and it keeps my iced drink cold for hours.

The double-wall insulation actually keeps my pre-workout cold all morning, which is a game-changer. The twist-on lid feels sturdy and the spout pops open easily even with one hand. Exactly what I needed for the gym.

The double-wall insulation keeps my water cold for hours, which is nice. The leakproof lid works well, though the pop-up spout feels a bit stiff at first. Overall, it's a solid shaker but nothing special.
