IRON °FLASK 40 oz Wide Mouth Water Bottle with Straw

Angie's honest notes

I've had this bottle for two years and four months, and it still looks like the day it arrived. I use it every single day and I take it everywhere with me.

Where it actually lives. On my nightstand. It's my little fridge at night. I fill it with cold water and when I'm thirsty at three in the morning I don't have to get up and walk to the kitchen. It's right there beside me, and the water is still cold. Not cool. Cold.

The cold, and the heat. Iron Flask says up to 24 hours cold and up to 12 hot, and that matches what I get. Cold water holds a full 24 hours for me, and if I drop in three ice cubes it stretches even further. Hot is the shorter side, around 12 hours with tea or coffee with milk. I use mine mostly for cold water, that's what I reach for.

Why it holds. Double wall insulation, so it doesn't sweat on the outside and your hand stays dry. Iron Flask lists 18/8 stainless steel, BPA free and non-toxic, and after two years mine has never left a metal taste in the water.

The spout. This is the part I didn't expect to love. One finger flips the straw up and you sip, that's it. The straw lives inside the lid, so it folds back down and closes clean. And if you'd rather not use the straw at all, close it tight and tip it up, it drinks fine that way too.

No leaks, none. I carry this bottle everywhere and it has never leaked. Not a drop, not even lying on its side in a bag.

How I use it through the day. I keep it full of water all day. I rinse it, refill with cold water, and drink from the bottle instead of opening the fridge or walking to the dispenser twenty times. That's the real convenience: the cold water comes to you.

What still looks new. The logo printed on the side hasn't faded, not one bit. The steel looks untouched. Two years of daily use is where you find out if something was made well, and this one passed.

Which size to buy. Mine is the 40 oz and I'd buy it again, but pick the size for your day, not for mine. The 40 oz is a big bottle and it will not fit a car cup holder. If you travel, or your bottle is going to live in your car, buy the 22 oz instead, that's the one that sits snug in the cup holder. Iron Flask makes several sizes in between, so think about how much water you actually drink in a day and how much weight you want to carry.

One more thing to know. Iron Flask says hand wash only with hot soapy water, so don't put it in the dishwasher, because that's how you ruin the insulation on any bottle like this. Mine rinses out in seconds, so it has never been a chore.

Skip it if you need something that fits a cup holder, or you want to throw it in the dishwasher and forget about it. Size down to the 22 oz for the car. But for a bottle that keeps your water cold from one day to the next, this is the one I recommend, and I recommend it a lot.
