แก้ว IceFlow™ Flip Straw Tumbler | 20 ออนซ์

The ergonomic shape fits my hand perfectly during spin class—no awkward grip even when I'm cranking up the resistance. Ice stays crisp until my last sip, and the flip straw is a lifesaver when I'm dripping sweat and don't want to unscrew a lid.

I was skeptical about the flip straw breaking after a few weeks, but it clicks shut firmly every single time. The 20 oz size is perfect for my spin classes, and my water stays icy cold through the whole workout.

The ergonomic grip makes it super easy to hold during my commute, and the flip straw pops up smoothly without any leaks in my bag. Water stays ice-cold for hours, which is exactly what I needed for long workdays.
