IceFlow™ Flip Straw Tumbler | 30 OZ

As a gym rat with zero patience for lukewarm water, this tumbler is a total game changer. The flip straw is super convenient and I love that I can snap it shut without worrying about leaks in my bag.

Snap the straw shut and toss it in my gym bag without a second thought—zero leaks so far. The double-wall vacuum keeps my water ice-cold through a full two-hour practice, which is exactly what I needed.

Used it all day at the track and then threw it in my gym bag without a single drop leaking. The flip straw snaps shut so securely, and the double-wall insulation kept my water ice-cold through a two-hour practice. Best tumbler I've owned for on-the-go sipping.
