Iron Flask Sports Water Bottle - 18 Oz, 3 Lids (Straw Lid), Vacuum Insulated Stainless Steel, Hot Cold, Modern Double Walled, Simple Thermo Mug, Hydro Metal Canteen (Sky)

The bottles are really nice and keep our drinks cool. We have 5 of these bottles. The only complaint I have is that the bottles are not 100% leak proof when using the top with the straw. If it falls on its side then whatever liquid you have inside will slowly leak through the straw, and even more if the spout is in the up position. I have twin 3 yr olds that love these bottles, and keeping them upright is a challenge. Also the spring has broken on both of their lids, and the spring sticks out a little when the latch is pushed in causing it to poke our fingers if we're not paying attention to how we hold the handle. Not a real big deal unless we're driving for on a trip and not paying attention to what the twins have done with their bottles, and come to the end of the driving finding a not nice wet mess in the back of the car.

Bought this for my son, I don't think I'll ever stop buying from iron flask. Bottles are just perfect, leak proof. Easy to clean. Highly recommended. Will definitely keep being more.

Great quality bottle. Bought this bottle on a sale and is probably one of my best purchases. Will be using this for the next like 5 years lol since it’s stainless steel. Comes with an extra sucking straw and 2 other lids. Soooo worth it. Highly recommend.

Great made multiple covers casings straw and cleaning unit

I absolutely adore Iron Flask bottles! You should just buy some!! Don’t even bother reading this review, okay? Just hit that back button and smash that Add To Cart button! Seriously. Go. Go now.Ugh, fine, don’t follow directions then, you rebel. Alright, well, I bought the 14oz in a blue hue, and the 64oz bottle in purple-ish. I only ever use the little one for coffee or hot cocoa. But not tea. Oh, no no, not tea. It’s important to keep the tea in its own bottle, which I need to purchase, otherwise it starts to get a big head, and starts correcting everyones grammar. No one needs tea sass in their lives. Keep ‘em separate, I say.Coffee and hot cocoa are like comforting liquid New Orleans jazz in a cup. They taste great, look great, make you feel great, and make you want more. Later, though, you realize you drank too much, and you can’t sleep, and you don’t feel great anymore. But, the next day, you wake up and you only know that you NEED more, especially in the early hours of the day. Other people might try to talk to you, the smaller ones might even want you to help them with something. They are oblivious to your caffeine withdrawal induced homicidal tendencies. You literally don’t remember how to human, all you know is you need the brown stuff in the cup.Shhh, there there. It’s okay, calm down. I’m very proud of you for not doing the murder! Go make the brown stuff. It will make it all better. Good job.The 64oz big ole bottle, and boy howdy is it, I use for cold beverages mostly, usually just water with ice. It already weighs quite a bit empty, so filling it up will force you to use both hands to get a drink from it. But it is absolutely worth the extra effort.Let me tell you, it’s been a few weeks since I started using them, and I couldn’t be happier with them.The 14oz keeps hot beverages warm for at least 6 hours, but I haven’t timed it to see if a beverage will stay warm for longer. I mean, I have other things to do okay? If that’s a problem for you, buy your own bottle and perform all the darn tests you like! Geez!My 64oz, so far, has kept ice frozen, with very little melting, for almost 3 days. Again, I wasn’t performing an official science experiment or anything, but it just happened like that over the course of a weekend. No, I was not being held against my will in a place where I didn’t have access to a sink. I’m just lazy, and didn’t feel like taking it to the kitchen after I drank all the liquid.
