Review: Great bottle - I love this bottle—great size, fits in car cup holder, easy to clean, and it keeps drinks at the perfect temperature.
Review: My fav water bottle brand - I own quite a lot of hydro flask bottles (you can never have enough.. or can you?) and they are by far my favorite water bottles to buy. They are sturdy. As you can see from the picture this water bottle went through some damages but it’s still holding up strong! I like how they offer may sizes as well and cleaning is a breeze. The bottle is insulated so cold water will stay cold for a long time and hot water will stay hot for a long while as well. You can clean it with a brush that fits the opening but i typically put it in the dish washer. Just a FYI to not fill it all the way up. It seems that if you fill up too high around where it bottle necks it tends to leak a little. Overall though I still love their products.
