Really nice bottle. Good to have the differnet top options for it. Great for gym, or whatever you want to use it for. Colour is delightful and is absolutely solid. Way better than plastic any day.

I bought this for my 4yr old. She loves the colors they are all her favorite. Perfect for her little hands not too small not to big. Will be the perfect amount of water for her for our summer outings & homeschool outings. 2 of the 3 lids are easier for her to drink out of. And it’s leakproof so I don’t have to worry about it leaking on her backpack/car seat. Also very easy to clean. I just used a baby bottle scrubber & a tiny amount of soap. What I love about the stainless steel water bottles is how long it keeps h2o cold in the hot summer heat. I live in MN but lately we’ve had 80 degrees or higher weather for spring. What I also love is when it’s dropped nothing of this water bottle breaks. It’s in perfect condition.💪🏼 This water bottle came with 3 different lids. The wide mouth is your type wide mouth. It came w/2 straws. The lid with the straw; the handle is like a little claps that can hook onto something. So if you hike this would be a perfect feature for you.

Loved this!! Perfect for my 2 year old to grasp and carry, clipped onto my diaper bag and Jean belt loop without being too heavy. Keeps the cold water super cold all day. Doesn’t dent easily when being dropped and the color doesn’t rub off when after being washed. Comes with 3 different types of lids and is easy to drink from. Doesn’t leak at all except what a liquid is already in the straw and that’s to be expected. Doesn’t corrode on the inside. I’ve had this for about 3 months

Excellent bottle. But for ice cold water, the Coldest Water bottle is the GOAT. The latter keeps its ice in the bottle long after the Iron Flask's had melted.

We have purchased these bottles multiple times for our 2 kids and have never had an issue. But I am not very impressed with the gradient colouring on the orange/yellow. It literally looks like someone just sprayed half of the bottle. I also got the cotton candy (teal/purple gradient) and it looks great. Love that their are 3 lid options and an extra straw with each so if kids break the plastic parts, the bottles still last forever!
