40 Oz Wide Flex Straw Cap Bottle - Insulated Stainless Steel - Wide Straw Lid, Non Spill, Leakproof in Dew

I use my 40oz Hydro Flask every day, and I’ve always lived how cold it keeps my water (or any other beverage for that matter). In the beginning it kept ice frozen and cold even overnight! However these last few months I noticed the insulation not performing as well, so I did the test to check for hot spots recommended on the Hydro Flask website and got a warranty claim going (I love that they have a Lifetime Warranty on all their flasks!), however since I’m having a baby soon I didn’t want to be without my HydroFlask during labor, so I ordered a new one to ensure I would have one on hand if they are still processing the warranty claim when the time to have this baby comes. I like the new updated straw lid style, the new handle is more comfortable to carry. The 40oz has always been the perfect size for me, I can meet my daily water intake goal by drinking 3 of them per day and I like that I don’t have to constantly be refilling it throughout the day. These are by far the best quality water bottles I’ve ever used, and between that and the Lifetime Warranty I am a HydroFlask loyalist for life! These also make great gifts too for anyone who likes always having their beverages ice cold like I do.

I absolutely love my hydro flask!! Keeps my drinks cold for a long time. I doesn’t melt unless it is in a hot car or in the sun. The drink stays cold.

Keeps liquid ice cold all day!! Bought for my wife and she loves it.

This keeps drinks cold for a long time. Great for golfing. Ice keeps for the whole round even in the desert heat.

Great product! My water is freezing cold after putting in ice every morning. Holds a lot of water and is totally leakproof.

Love the color and style. The straw is sleek and easy to use. Keeps water cold. Overall happy with the purchase!

I use this thing every single day- work, hiking, running errands, etc. I originally bought this to keep in my backpack at Burning Man and it kept me alive in the desert heat. I used to use smaller bottles, but 40oz is the perfect size to make sure you have plenty of water when heading out for the day. Keeps my water cold and helps me drink more water overall bc it's more fun to drink out of a straw!

I just love this Hydro Flask water bottle. I am a big water drinker and ice in my drink is very important to me. This is one of the best water bottles I have used so far. It keeps my water cold all day and over night. I have to take the old ice out and fill with new before I would ever think I needed too. I have not tested it with hot drinks so I Cannot speak to that as yet.
