Hydro Flask 40 Oz Wide Flex Cap White

The Hydro Flask 32oz water bottle has quickly become my go-to for staying hydrated throughout the day. It hits the sweet spot in size — large enough to keep me hydrated for hours without being too bulky to carry around. Whether I’m at the gym, at work, or on a hike, it’s the perfect companion.The insulation is seriously impressive. My water stays ice-cold for literally the entire day — sometimes even into the next. I’ve also tested it with hot beverages during the winter, and it performs just as well. The double-wall vacuum insulation does exactly what it promises.Design-wise, it’s sleek and simple but still feels durable and high-quality. I opted for a matte finish and it not only looks great but also gives a nice grip. The wide mouth makes it easy to fill, clean, and add ice cubes, and the lid seals tight with zero leaks. I also love that it fits in most cup holders and backpack side pockets, despite the larger size.If you’re looking for a reliable, well-designed water bottle that keeps your drinks cold (or hot) for hours, the Hydro Flask 32oz is absolutely worth the investment. It keeps me drinking more water, and honestly, I kind of look forward to carrying it around.

So far it's great - nice color and beautiful design, very durable due to being metal, fatter than most other metal bottles so it doesn't fall over so much (could be even fatter like a Nalgene). It has developed a slight nasty smell but you don't notice it unless you're paying attention. The handle is probably unnecessary, it's easier to just hold the bottle usually. The main issue is that it's kinda heavy -- due to the whole microplastics thing I would have switched to a metal bottle much earlier if not for the weight, but I guess that might require new technology to solve.

Love it. I got this for my elderly father, upgrading it with the metal lid. It’s of a perfect size, and not at all heavy for him to carry around when full. It keeps its hot contents hot and cold contents cold. It’s a big improvement for his single walled flask which could not be used for hotter liquids. Even when wet the texture gives enough grip to prevent slipping. The wide mouth also makes it easier to get a brush inside and clean along the tapered portion.I have the 64oz, which is another wonderful product, but this one hits the mark in so many ways.

This is a GREAT water bottle. With the wide mouth, it is easy to fill with ice. It is not as huge as some bottles, which was one of the reasons that I chose it; it is not bulky, it's easy to hold, and it fits in our car's cup holders. A bit pricey, but this is a quality item. Used it today and it kept my ice water COLD. Now my husband wants his own! My research paid off. Go for it!

I love this water flask. So much better than drinking out of plastic bottles! I purchased a wider opening and it's a breeze to clean. It keeps contents cold. I haven't put anything hot into it yet but I believe it would not disappoint. It's almost like a pet to me so I purchased a couple of vinyl stickers to adorn and personalize it. 😁 (A lion and owl in medieval manuscript style.) Fun.

I don't know why, but the lavender/light purple version of this bottle chipped and dented far more easily than any of my other hydro flask.I also have this in a baby puke green and turquoise. They have held up wonderfully through heavy use and being taken everywhere. They get 5 stars.The purple one is a fluke, sadly. The color is gorgeous. I am still giving this review 5 stars because these are all I've used for almost 5 years. However, my heart breaks for the purple bottle that couldn't.

I bought this thermos to keep water hot for making bottles for my picky baby when we were traveling. It did a good job keeping the water warm enough for her for up to 8 hours. However, I had problems with the rubber inner seal falling out. This happened when TSA would check the thermos and it was a big inconvenience. I imagine this happens when you put hot water in it but still, it’s a drawback.All in all it worked well for me and it’s a beautiful color.

This is solid water bottle that keeps liquid cold / hot. It doesn't leak, easy to use. My wife used it for about an year now and is very happy with it. Easily fit in her bag pocket.
