The flip straw mechanism clicks into place so securely that I tossed it in my tote without a second thought. The 20 oz size is perfect for my daily coffee, and the lid feels sturdy enough to survive my commute.

I was worried the flip straw would leak in my bag, but this thing stays totally sealed until I pop it open. The 20 oz size is perfect for my desk—I refill it maybe twice a day and the straw makes sipping effortless.

The flip straw lid is a game changer—I can toss this in my bag without a drop escaping, and the 20 oz holds just the right amount for a full afternoon. The built-in straw is sturdy and easy to flip open one-handed, which I appreciate during meetings.
