  • Don't Let Anyone Steal Yours!
Size: 40 Ounces Color: Dark Night
My daughter gave me one of these 40-oz Iron Flask bottles for my birthday in April. It comes with three different types of lids, for different situations or preferences, and it was just AWESOME. I babied it for a few weeks around the house and in my workshop. But on the third day that I took it to my day-job, someone stole it when I wasn't looking. I loved it so much that I just had to get a new one. There are a lot of color options to be attractive to pretty much anybody, but the durability and overall quality of this product is impressive. If you don't mind paying a few extra dollars for a higher quality product, this should be your go-to thermal bottle for work, recreation, sports, hiking, camping, fishing or even long drives. Now that I have this one, I want to get another one in a different color. Just don't let anyone steal yours, because people recognize quality when they see it. ... show more

  • Will Keep Beverages Cold!
Size: 40 Ounces Color: Pearl
I bought this bottle, trying to replace some Hydro Flask bottles that prematurely had the seal break. I had regular expectations for this bottle. I wasn't looking for anything more that to carry my water for the day at work. But this bottle set the bar high for any other bottle I may buy in the future - if it's not one like this one. It truly is insulated and keeps your beverages cold for a great deal of time. I filled the bottle up with ice and added water and went on a work trip. By the next morning, I went to fill the bottle up with water and was surprised to see that there was still half a bottle of ice left. By the following morning, I filled it with water again and it still had a quarter of the bottle with ice. This was during the summer and I never added ice in the entire time and it took 4 days to melt fully. I love this thing! ... show more

  • Keeps water cold for hours in the hot sun
Size: 40 Ounces Color: Midnight Black
Needed something that keeps water cold for a long time while I'm on the pickleball/volleyball court for hours. This is it! I had ice cubes and water in this thing and left it in my hot car while I went running for 3 miles, then I hit up the pickleball court and played for about 2 hours lol. When I got home there were still ice cubes left in the water bottle and it was upper 80 degrees out the entire time I was away! I got this one and the 64oz jug for longer pickleball sessions. ... show more

  • Had it for a 6 months and can take a beating
Size: 64 Ounces Color: Bubble Gum
I’m a welder and fabricator, I take this with me everywhere I go and with the different lids it makes the bottle very versatile for carrying and usage, I’ve left it in my car in the blazing sun and come back 8 hours later with ice still chilling in it the quality is worth the money. I’ve never had leaks and it can take a beating. The size is just enough store plenty of fluid if you need a quick pick me up after doing activities. I am tempted to buy another one when they restock the big sizes since the design is perfect👌🏽 ... show more

  • Love it
Size: 64 Ounces Color: Aurora
Keeps my water cold for several hours- not quite all day, but close enough. Color looks great in person. Big enough to hold all the water I need while out and about. Worth the money for sure. My only complaint is that I dropped this bottle once, just days after getting it. It had the added rubber grip at the bottom. The bottle dented and the paint scratched right off, even though it only fell from about 14" away from the ground. I haven't dropped it since because I bought a paracord handle for it, but for what I paid, I'm a bit upset that the bottle was so easily damaged. ... show more

  • Love this bottle!!
Size: 18 Ounces Color: Day & Night
I left the house at 830am on my motorcycle with this water bottle mounted on the handle. It was full of water and some ice. The temperature was 92 with a heat index of 105. I rode for 3 hours, had lunch, rode 3 1/2 home and the water bottle stayed on the bike all day. The water was very cold all day and it still had ice in it when I got home. I love this water bottle. You will not be disappointed if you buy one of these. I have the 18oz. ... show more

  • High quality and functional
Size: 40 Ounces Color: Twilight Blue
Love this bottle. Keeps ice pretty much all day and not much melting at all. Holds plenty of fluid and the straw drinking option is fantastic to use. The carabiner hanger is nice, and I also added a paracord hanging accessory to it, so it gives me options for carry or keeping in my vehicle when driving. I use this every day and works great and is very high quality. I looked at other brands and never had an Iron Flask brand but will certainly buy this brand again. ... show more
