    Cool Water Bottle

    • Familiarity: I've used it several times

    This is a great water bottle that keeps water crazy cold and the ice doesn't melt for hours. My only complaint is how heavy the bottle is. I wouldn't use this on a hike but great for around town, at the pool, on the boat or at work.

    Keeps cold things cold

      I had pretty high expectations of this bottle when I purchased it. It's a pretty popular brand and I see them in the office and on the trail. So I pulled the trigger on this bottle to see what all of the hype was about.

      This bottle will keep your drinks cold, or hot, whichever you want. I also really like the width of the bottle. It fits in most of the cupholders I've tried just fine.

      My only gripe is the lid. Sure, the handle on the lid is comfortable to carry but I have tightened the lid a considerable amount and was confident it would seal in the water. But when the water was tipped on its side, water would slowly leak out. When it's closed super tightly it does seal in the water, you just have to crank down the lid.

      New lid is everrrrrrything!

      • Familiarity: I've put it through the wringer

      If you have seen any of my other reviews on Hydro Flasks, you know I love them with my whole heart. SO there is really nothing I can say other than I'm seriously loving the 40 ounce. I don't think i'll ever use a water bottle that is less than a 32 ounce again. The 40 ounce keeps me hydrated allll daay looong. NOW. Let me talk about how much I love the newly designed lid for the wide mouth bottles. It is the best! I love it so much more than the old design. It's super comfortable to hold and carry and feels very sturdy. Hydro Flask definitely made a smart decision on redoing the lids.

      Best bottles ever

      • Familiarity: I've put it through the wringer

      I've been using my hydroflask for two years straight, no other bottle will do. We've been through some spills together, so it's got some dents here and there but it still works like a champ. I put ice in it in the morning and it's still kicking at night, after multiple refills! I've since purchased a bottle for everyone in my family and made a believer out of them all. Heads up, they can get pretty heavy when they're full of icy water so keep that in mind if you are trying to pack light!

      Simply Put, the Best.

        I ordered this bottle after a few friends turned me onto this company. I am one to constantly be drinking water and bring my liter bottles with me everywhere. I live in the Coachella Valley (Souther Cali) where during the summer months it reaches and easy 105+ degrees. The first day I received this bottle, I filled it halfway with ice and topped the bottle off to its brim with water... I then left it in my car, outside, directly in the sun while at school where temperatures reached 116 degrees Fahrenheit. I came back to my car 9 hrs later, not only was the water absolutely cold, the ice cubes hadn't melted in even the slightest bit. Couldn't be happier, buy one.
