Keeps me hydrated
Great water bottle. I wanted something that would fit my car’s cup holder, hold enough water to keep me hydrated on the go, and didn't have a lot of parts to keep clean. There’s nothing more frustrating than a water bottle that doesn’t fit your cup holder and many of the ones that do end up being too small to hold enough water to matter. This one is a great size for me, keeps water cold and the opening is big enough to add ice if I want. The lid is simple, with a carrying strap. Over time I’ve had various lids with straws or fliptops that either leak or get gross and are hard to sanitize. This one is simple to keep clean, and equally important, doesn’t leak. Love the color, functionality, and durability - I would give it more stars if that was an option.

great water bottle but...
I got this size water bottle because it's not too big and not too small. I just used this in a Chevy suburban and the bottle fit just right in the cup holder. I got the lid without the straw and it has a nice carry handle. I will buy the lid with the straw for future use because it is not easy for me to drink from this bottle when the car is in motion. the car stopped and I wasn't paying attention and the water spilled on me. if I had a lid with a straw that would've never happened. the bottle is good as is for hiking because I can just stop and drink from my bottle. if you intend to use this in a vehicle I would get the lid with the straw. the bottle kept my drinks cold. didn't test it for hot drinks yet as I am writing this review in the summer. it was a little pricey for my usual budget but I find it is worth it because so far the bottle is very durable and it seems it will last a while. the bottle is also easy to clean. so far so good!

Great high quality water flask
Great high quality water bottle. Have been using this for the past 2 years and will continue to use Hydroflask bottles! Liquid stays nice and cool or nice and warm. Easy to use and very functional.

I am both pleased and impressed!
It about wore me out looking at insulated bottles with so many out there to choose from! I am a heavy coffee drinker and wanted to be able to carry a nice, fresh refill for my travel mug while out and about. I will begin by saying that the first photo in my review, does NOT accurately represent the actual color that I purchased, Agave. The fluorescent lights in my shop are not color friendly. The actual color is a soft greyish green, like sage leaves and is very pleasant. Edit to ad: We had a spot of sunshine on the back porch today, so I took it out in the sunshine for a better pic. Much better color representation in the last picture. Initially, I was looking in the $20 range and found a lot of products that were "close" to what I wanted, but no cigar. After looking at the Hydro Flask page and seeing that accessories and replacement parts are available, I decided it would be worth a try. At the steeper price, over twice the price in many cases, it was worth it to get exactly what I wanted. My search criteria was as follows: * A Wide Mouth: For ease of filling, cleaning, easy pouring and nice big gulps. No straw or spout to clean or fiddle with. . *A Plastic Stopper: Because stainless on stainless threads are prone to galling. * No Big, Fragile or Obtrusive Handle: Didn't want something that would break off or get in the way or a lanyard to collect crud. This handle is small, folds back unobtrusively and is flexible so shouldn't break if twisted or bumped. *Easy to fill with hot liquids or cold beverages with ice. *A Centered Spout: So I didn't have to look and align it every time I took a drink or poured from it. *Cup Holder friendly in my old Jeep *Nice color *Sturdy construction This has absolutely ticked all of the boxes. It's slim enough to hold comfortably, very attractive without being showy and well constructed. I think we're going to be coffee drinking buddies for a very long time.

Leak-Proof and Durable at a Great Price!
I was late for a flight and hastily emptied my water bottle before lining up to for security. Apparently TSA was feeling power hungry that day and the two droplets remaining in my water bottle presented too great a risk. As they wouldn’t let me drink it or shake it out (which she could have done over the floor without a mess for how little was left) I had no choice but to allow her to throw away my 40$ bottle filled with stickers from my travels. This flask was on a great sale and I actually like it better than my original. There are no gaskets so nothing to get loose or moldy, just a sturdy almost vacuum seal. It’s durable and doesn’t show dirt from my hiking trips. It keeps things cold even in the sweltering summer months. All I need now is about 10 vacations to replace the stickers 🙃

Great product for the price
The color looks just like the image and the quality is top tier, very sturdy and convenient to use. However, gap between the handle and the screw near the lid picks up dust easily.

Great metal bottle
Got this when it was on a slight sale. Insulates in my hot car really well. Definitely one of my nicer bottles and fits in the cup holder. The cap stays on really tight. Takes more effort to unscrew than other bottles.

Super bien empaquetado Lo conseguí en descuento por hot sale y aún sin este aquí es mucho más económico que la página oficial. En textura tiene un toque de rugosidad que mejora el agarre, en general se siente de buena calidad. Útil para llevarlo en la mochila sin riesgo de derrames por su tapa 100% hermética. El color es un gris verdoso, muy minimalista o sencillo, sin ser ostentoso.

Great opening for ice and keeps everything super cold for hours! Love the wide mouth opening and tough exterior. I’ve dropped it dozens of times and still good!

Muy bonito, resistente y de buen tamaño. Al no ser un termo muy grande tampoco es muy bultoso o pesado, lo cual se aprecia. El color es muy bonito y la textura es como rugosita. Mantiene el agua fría muy bien durante todo el día.
