    • Great Insulation, Perfect Size
Style: 32 Oz Color: Black
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. ... show more

    • Yes. Always hydroflask.
Style: 32 Oz Color: Black
Always my choice for water bottles. I have owned many. They have have survived many camping trips across the US. From falling down a cliff side while rock climbing, rolling around the bottom of a canoe in the boundary waters, or even getting slammed in the hatch of a jeep. It’s held ice for over 24hours when I’ve needed to keep cool on hot hikes and has also kept things hot when I’ve found myself camping in a multi day rain storm. ... show more

    • Great purchase - I bought another one!
Style: 32 Oz Color: Black
Nice big water bottle that holds a lot of water. I like that the top has such a wide opening to make it easy to clean. The lid seals securely and the bottle is very durable. The only thing to keep in mind is it won't fit in your car cup holder. But the lid is so secure that I can toss it in the seat next to me without any concerns. ... show more

Perfect! Great size, no leakage, keeps the drink cold, doesn't affect the taste, great grip! Hydro flask is the only bottle worth buying IMO

    • Great water bottle
Style: 40 Oz Color: Indigo
The bottle keeps my cold water cold for an incredible time, its made of healthy materials and it is very durable. While it is on the more pricier side, it looks that it will last forever, which means: until I will loose it ;-)

    • Beautiful and functional
Style: 32 Oz Color: Surf
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. ... show more

My wife loves the color, she mainly uses it for cold liquids and it maintains temperature pretty well. Only downside is the handle changed color, that’s her only complaint. It has yellow tint to it.

    • Great!
Style: 20 Oz Color: Black
Hydro-flask quality is second to none. I bought this to replace my 15 year old 20oz. I’m still keeping the old one It for a backup. Perfect size for cupholders. I also have a 32 oz 15 year old going strong.
