Marie 防漏 Cruiser

Tossed this in my tote with a full laptop and not a single drop escaped during my whole commute. The twist-lid design is genius—so simple but actually works.

I've had this thing in my bag for three weeks straight, riding the subway and jostling through crowds, and the twist lid hasn't leaked a single drop. The 22oz size is perfect for my whole workday without needing a refill. My laptop stays dry, and that's all I really asked for.

The twist-lid seal is no joke—I tossed it loose into my work bag right beside my laptop for two weeks and not a single drop escaped. At 22oz it's the perfect size for my daily commute, and I've stopped double-checking my bag every time I set it down.
