Helps with my hydration goals
I love my pink Hydro Flask! The color is so cheerful and looks great sitting on my desk at work. It keeps my water cold for hours, which makes it easy to stay hydrated throughout the day. The size is just right, and the quality is exactly what youâd expectâsturdy and well-made. Definitely a functional and fun addition to my daily routine.

Absolutely love it!
Most people talk about keeping ice/old water, but I wanted a bottle that performs well with both cold and hot drinks. This bottle kept my hot tea extremely hot (which I liked) for over 8 hours. I like to keep hot drinks in here and pour it into a smaller cup for drinking. Absolutely love the color and size of the bottle! It will keep me well hydrated in Alaska.

All around great quality and easy to clean.
Iâm not big fan of bottles with built in straw or something similar because itâs not simple to clean.This Hydroflask water bottle has a simple top which I like, easy to drink out of it and way easy to clean, besides the 32 oz size is just right for me, gets me through the workouts or workday.

Good quality
. My daughter loves it . Only prob is after a while it started to get a bad smell from being used so much. I would wash it air dry it and the smell wouldn’t go away.. its pretty sturdy. Got dropped a few times after the 4th time it got a dent but it did go thru a few drops before that.

Elle garde le froid, je n’ai pas encore testé le chaud mais une amie l’a depuis plusieurs mois et elle me confirme l’efficacité du produit sur ce point. Elle est légère et plus intéressant, vu que c’est une gourde en alu sans BPA, elle n’a aucune odeur ni goût désagréable comme on pourrait s’y attendre avec une gourde standard. J’en ai déjà recommandé une !

Este termo es bastante bueno para llevar café en las salidas en bicicleta, la capacidad es adecuada (más o menos dos tazas) y mantiene el calor bastante bien.Una noche que estuvimos cerca de los 0°c puse agua caliente dentro del termo, y a la mañana siguiente el agua seguÃa caliente, obvio no tan caliente como la deje en la noche, pero si lo suficientemente caliente para ser agradable al beberla.
