IceFlow™ Tumbler med flipstrå | 20 OZ

Took this from the court to the gym all week and the double-wall vacuum actually kept my water cold through a two-hour practice. The flip straw pops up easily even with one hand, and snapping it shut means zero leaks in my gym bag.

The flip straw seals tight enough that I tossed it in my gym bag without a drop leaking, and the 20 ounces is just right for a full practice. Double-wall vacuum keeps my water cold through two hours of drills, which is exactly what I needed.

Bought this for weekend games and it’s survived being chucked in my gym bag without a single drop escaping when the straw’s snapped shut. The double-wall vacuum keeps my water icy for the whole match, which is exactly what I needed.
