My daughter takes this to school every day and the water is still icy cold at pickup. The Koala Gray hides scuffs nicely and the straw cap is easy for her to open by herself.
Dented corners? No. Chipped paint? No. Still looks brand new after ten months of being thrown in a backpack. Worth every penny.
The straw takes a little getting used to for cleaning but the bottle itself is fantastic. Ice stays overnight, which blew my kid's mind. The boot has saved it from countless drops on the driveway.
Maybe ours is defective, but water seeped out through the straw even when closed. Two soaked homework assignments later we switched back to the old bottle. Insulation is great though.
Fills it at 7am, still cold at bedtime. Kid loves it.
Good quality as expected from Hydro Flask. My son says it's a bit heavy when full but he manages fine. The gray color is nice and understated, not babyish.
We keep buying these for each kid as they start school. The straw cap is the winning feature — no unscrewing, no spills, no lost lids. Easy to clean with a straw brush.
He actually likes using it, which means it comes home. That alone earns five stars. Cold all day, no leaks, easy grip for small hands.
The 18 oz goes fast for my big drinker, so he refills twice a day at the fountain. Otherwise well made and keeps things cold. Maybe size up if your kid chugs water.
I was nervous about putting it in the dishwasher but it's held up perfectly for months. Grandma bought the boot as an add-on and it fits snug.
We've tried cheaper bottles and they always crack or leak within a semester. This one is still going strong after a year. Only knock: the straw gasket needs occasional deep cleaning.
