The IceFlowTM Flip Stro Tumbler | 30 OZ - Stanley Create

Filled it with ice water before a 6am practice and it was still freezing when I finally finished it at noon. The flip straw snaps shut so tight I threw it in my gym bag without a single leak, and the 30 ounces is perfect for a whole game. Honestly, I can't stop grabbing it over my old bottle.

I’ve been hauling this thing from my car to the gym and then straight to my kid’s soccer game, and the leakproof snap lid has survived every toss. The vacuum insulation actually keeps my water ice-cold for the whole afternoon, which is a game-changer when I’m running around.

The flip straw is so convenient when I'm walking from the parking lot to the gym, and it's genuinely leakproof once you snap it shut. I've tossed it in my gym bag sideways and not a single drop came out. The double-wall vacuum keeps my water ice cold through a full two-hour practice.
