I love this! I’m a Stanley girl through and through, but my other Stanley’s don’t have the flip straw. Being in nursing school, I almost never have any hands so being able to place this into my bag is HUGE. I can throw it in any bag I have and not have to worry about it spilling anywhere! Stays cold for hours!
I would recommend this to a friend!

Great tumbler bought a second for my dad that had previously been using Yeti. I think since the straw flips down it keeps it colder longer than the yeti one.

I found a free Stanley on the street . If Stanley’s were so good why are they on the road?
No, I would not recommend this to a friend.

The only complaint that I have about that bottle is the top is very hard to screw on to get it on correctly.

I love these I’ve actually bought 3 of them soon to be four. The only thing I don’t like is that the lid chips easily.

Gym Essential: The Perfect 40oz Hydration Beast!

The Stanley IceFlow 40oz with Flip Straw is an absolute game-changer for my gym routine. It keeps my water ice-cold for hours, even during intense workouts, and the flip straw makes sipping mid-set effortless—no spills, no fuss. The 40oz size is spot-on; it’s enough to power through my session without constant refills, yet still easy to carry with the sturdy handle. Durable, leakproof, and exactly what I need to stay hydrated and focused. Stanley nailed it!

My wife was using the Stanley Quencher 40 oz but the handle was constantly getting in the way of the gear shifter of the car. So, I purchased this as a solution for her and she absolutely loves it and has stopped using the other model completely. It seems to keep the water equally as cold and she likes the carrying handle and the straw that is built in and reaches the bottom of the mug. I think this product is a home run.
I would recommend this to a friend!
