This is a great product! Keeps ice for over a day, water stays cold. Drink spout is easy to deploy and closes securely. The jug can leak if the lid is not tightly closed, but that would be true of any product. I'm looking forward to really using it this summer when the weather heats up. The 40-oz capacity is a good size, too: enough water for a hot day, but not hugely bulky like some products.

All the negative product reviews on this website are odd. In some cases, the review sounds like it is for an entirely different product. And it would be much more helpful to see reviews from actual REI users as opposed to dozens of comments from Stanley's website.

I LOVE this tumbler! I fill it daily with ice then add my protein drink. It keeps my drink very cold all day and the ice slowly melts so I get water the rest of the day. The flip top is great for ensuring no spills and staying clean. The next morning there is still about a cup of ice in the tumbler! I gave only 4 stars because the straw is initially difficult to use with ice - the ice gets stuck to the sides and it is hard to insert the straw because of this. I've tried inserting the straw before adding ice, and the ice won't move so the straw comes off the grommet on the lid when twisting the lid on. I also would love a stainless steel straw option. None of these are game changers for me. I'd buy another in a heartbeat!

Love it & the color. Gosh Stanley been around since I was a kid. I would see factory workers with them. I remembered the commercials back in the seventies. I was never much of carrying things except my bag. I wanted to see what was the hype now in my sixties. I purchased two one for my 9 yrs old granddaughter as she knew about Stanley & all the kids at school had one. This 4th of July I used mines at the park. My favorite drink Coke stay COLD for the 12 hrs in the hot sun until finished it. I mean COLD, not a little cold. Now I am sold & can’t wait to give my granddaughter hers when school starts in September. Definitely the real deal for less than $50. PS: I purchased a purple crossbody one for $75. Great for long walks & bike rides. Don’t tell my kids 🤫

After going back and forth between the 40oz and the 64oz for some time, I’m ultimately glad that I decided to go with this size. I’ve now been using this water jug for a little over a month and have been extremely pleased by its quality and how long it keeps your drinks cold. I filled it up prior to a weekend camping trip Friday morning and by Sunday evening after replenishing some water it still had a very good amount of ice left in it. This water jug has also been great for my job because I work long shifts at a warehouse and it’s been very helpful to have extra water throughout the day. Prior to purchasing I read some negative reviews that it leaks and complaints of buyers receiving the wrong size or color but I didn’t experience any of that. Overall very very happy with my new water jug!
