Love the color. The coating is very durable. Great insulating properties. The top is made of high quality dense plastic with a rugged seal. The handle feels like it will hold strong but I haven’t tested the limits. Fasteners for handle compliment the overall design and are high quality machined stainless.

It’s not the first stainless water bottle I’ve ever had. If I need another insulated bottle in the future it will be another Hydro Flask.

Highly recommend.

I purchased this bottle because it was on sale and it is a great bottle. BPA free. I put ice and filtered water in it, and the ice lasts for at least 24 hrs sometimes longer. It does need a strap to hold on to it and it not slip out of your hands.

Let me start by saying that hydro Flask has a great marketing team which has made their water bottle extremely popular and trendy. My daughter saved her money for this water bottle which was quite expensive in my opinion however she was excited to purchase it and use it for school. When we opened the package it was dented. Although I am sure will work as intended it took away the aesthetic. I will return the water bottle or reach our for an exchange. Hopefully their customer service is just as good as their marketing! ⭐️Update: we ordered a replacement came the next day, now we are 😃 happy lol!

I have been wanting a hydroflask but couldn’t afford it. So I was so glad when it went on sale and they have the color that i liked! The temperature really stays longer. I always use it for my hot water and it lasts for hours! The sturfy material doesn’t make me flinch whenever I drop it on the ground. I had several drinking bottles before but they always get a dent when I drop them. This hydroflask doesn’t even get a slight scratch on it. I highly recommend this product!

According to the description there wouldn't be a metallic taste, but I have noticed a metallic taste. This usually occurs when my water (no ice) has been in the bottle for hours on end. However, the appearance of the bottle is nice & you can tell it's well made.

As far as the staying cold test here's what I have to say:
-If I didn't use ice, my drink would only stay fridge cold for about 5 or 6 hours max.
-I haven't tried hot drinks.
-The Hydroflask bottle seems to keep ice not melted for an extended period. I could easy say ice will not melt in a 24 hr. period.

Overall, I think there are other brands out there that can perform just as well as Hydroflask for the same price or cheaper (Yeti?).

Es muy lindo, el material es metálico y agradable al tacto, mantiene bien las bebidas, pero si te decantas por este tamaño hay que ser consciente que si es difícil de manipular (como al traerlo en una mochila o bolsa) hay muchos lados en los que no cabe porque si es grandecito
