Cold water, fits in cup holder and doesn’t spill

KatieJanuary 4, 2026

This is the best water bottle for when you’re out all day! The ice never melts and holds a lot but fits in the cup holder. Very easy to clean. I have now bought 3 of these to gift to others as well and they always love it! I used to take my Stanley with me but it does spill where as this one does not so I can throw it in a bag and not worry about it while bringing groceries inside or attending the kids games ect Read more

Best water bottle ever

APNovember 28, 2025

Love, love, love these water bottles. The handle on top is strong and sturdy. I love the flip top and straw. The metal bottle keeps iced drinks cold for hours and bottle will only dent slightly when dropped on concrete. Read more

Cup holder approved!

Love my new 32 oz Hydro Flask Travel Water Bottle. It fits perfectly in my car (Honda Accord) with or without the boot. I purchased the small Hydro Flask boot in sandpiper (grey brown) and it is stunning against my agave green bottle. I love that the lid, spout and handle are all agave green. Stainless steel construction is worth it for a bottle I use everyday. Easy to clean. It does not leak and keeps water cold, even ice cubes don't fully melt overnight. I also own the 32 oz Hydro Flask Travel Tumbler with the handle. I use the handled one for the house and the travel bottle for work and travel. As you can see, the Bottle is basically the Tumbler with out the handle and taller because of the lid. They are both 32 oz in the pictures. While the Travel Bottle is a bit taller than the Travel Tumbler, it will just fit under my ice maker/water dispenser. YMMV depending on refrigerator you have. I am pleased with my purchase. As always, Hydro Flask has been a great brand to purchase from. Read more

Decent water flask. Okay for the money

Sassy Silver GramsNovember 11, 2025

Good quality, but not 5 stars on the functionality aspect. I really must make sure the cap is threaded completely tight and properly and the flip straw goes down slowly or there is spillage/leakage. Once all that is in order, it doesn't leak. Sometimes I'm in a rush and water gets under the flip down straw part and then leaks. A little frustrating. Not sure if it's a design flaw or just operator error. But the stainless steel is good quality and powder coating holds up well until it is dropped on asphalt. My bad. The insulation does it job pretty good. Read more

Buy it for life enthusiasts, rejoice

Miss MusicOctober 21, 2025

I love this water bottle. After much diligent research, I debated between a couple brands but ultimately decided to spring for the Hydro Flask because of their reliability with insulation as well as it being able to fit in my car's cup holder. A friend gave me a 21 oz one as a gift, which was excellent for in office use but not for driving because it had a screw top. Originally, I started to use this one around the house, just to see if I liked it enough before testing it while driving. It's replaced my glasses (sorry, dishwasher). Though I loved my Contigo that had the one touch button, it didn't keep my water cool over an extended period of time. The water (both room temperature with some ice cubes added and refrigerated water) remains cool even when it's too hot outside. The water bottle is easy to hand wash with dish soap. A bottle brush comes in handy for the straw. The draw backs are minimal. You need to be careful with the water bottle so it doesn't dent or scuff. The flip straw takes a little bit of getting used to; there's a small depression in the tab that you press to open the straw. Though this water bottle is a bit more expensive, it's worth it because it's one you will keep for a long time, provided that you take care of it. Read more

Good quality!

Momof4azDecember 3, 2025

This is good quality, However, it tips over easy if not in a cup holder, because the base is small and it becomes top heavy when full and it tips over when just bumped. Read more
