I filled the white flask with water with a few ice cubes and the ice cubes were not melted 5 hours later at lunch when i drank the water

My only beefs might be 1 the lid when unscrewing with liquid inside is a little prone to dripping on the desk so have to be careful and 2 not dishwasher safe and not the easiest thing to wash by hand

Edit after another few months the strap holding the cap broke

It would have been a five star if it didnt chip right below the mouth piece the first time i used it

Took off a star because the cap attachment is very prone to breaking

One badgood thing about it is the big opening its good because you can fit ice so if you enjoy ice cold water but its bad because you cant drink while walking at least from my experience any movement would result in water spilling

I specifically waited to see if that would be an issue

Unfortunately i dropped it on a rock twice and it dented and the vacuum seal broke so now it doesnt insulate
