  • Reliable
Style: 24 Oz Color: Tonal Agave
at 1st I was a bit disappointed, thought the colour looked more grey than green. But It is a sage green with grey logo print and definitely does look green in the light. It's a much more muted green than some of the other colours. The bottle itself is great. The lid is easy to drink from and looks easy to clean. It keeps water cold for a very long time. I've had hydroflask for a long time and bought a new one since I knew the quality is good and is very durable. I'm very prone to dropping bottles and hydroflask has never let me down. The handle is great too and way easier to carry than my previous one of around 3 years. This is my 1st wide mouth so I look forward to seeing how it performs ... show more

  • Keeps Water Cold All Day – Perfect for Hot Arizona Summers!
Style: 32 Oz Color: Stone
I bought this for the Arizona summers because other water bottles never keep my water cold. This one stays cold for 24 hours, which is amazing! It’s very sturdy and definitely worth the price. The water does not leak even if it falls, and the handle makes it easy to hold and carry around. It doesn’t fit in a normal-sized cup holder since it’s not small, but it carries a lot more water than the average bottle, which is a big plus. Plus, it comes in really cute colors. One tip: I recommend getting small cleaning tools to keep the straw lid clean because mold and dirt can build up over time. Overall, a great purchase! ... show more

  • Would buy again
Style: 32 Oz Color: Oat
I’ve been using the 32 oz Hydro Flask with the straw lid for a few months now, and it’s become my go to bottle every day. The size is perfect it holds enough water to keep me hydrated without needing constant refills, but it’s still easy to carry around. The straw lid is super convenient, especially when I’m driving, working out, or just don’t want to unscrew a cap every time I take a sip. The insulation is amazing it keeps my water ice cold literally all day, even when I leave it in my car or take it on long hikes. I also love the wide mouth opening because it makes it easy to add ice cubes and clean. The powder-coated finish gives it a great grip and hasn’t chipped or scratched, even with daily use. Yes, it’s a bit more expensive than other bottles, but the quality, performance, and durability make it 100% worth it. If you’re looking for a reliable, high-capacity bottle that’s easy to drink from and looks great, I highly recommend the 32 oz Hydro Flask with Straw Lid. ... show more

  • LOVE THIS BOTTLE!
Style: 32 Oz Color: Jelly Pink
I love hydroflask for all things water and drink related! I hate drinking anything that isn’t at least somewhat cold, but I prefer really cold drinks, and I live in the desert. It also doesn’t leak so I don’t worry about that. All of these bottles can dent but I care more about the functionality, and honestly with a boot and being somewhat careful, I rarely have issues with that! For water I have a 40 oz cup, a 32 oz cup, and now this 32 ounce flip straw. It doesn’t leak, it’s super effective, keeps the drinks cold. The handle is easy to use and feels secure. The color and appearance is gorgeous and unique. I love it. It’s my new go to! ... show more

  • High Quality-Stays Cold
Style: 24 Oz Color: Aloe
Love my Hydro Flask bottle! Keeps liquid cold all day—I even routinely find ice still in the bottle the next day. Very well made. Like the sippy straw (tip—it must be in the full open position to work). And the color options are great particularly the new tonal colors. The 24 oz fits in my cup holder. Will be the only brand I order going forward. ... show more

  • Good quality water bottle!
Style: 32 Oz Color: Indigo
I was pleased with my purchase. I took my bottle to Egypt with 95-113 degree heat. I wouldn't say the water stayed "cold" the entire time, but it was cool enough to be refreshing. We were advised not to use ice because local water has a high chlorine percentage, but I think that ice would have helped the water stay cold. Worked well. No spills, good seal. I dropped it a few times, and there were no dents. Good rugged bottle. ... show more
