Can anyone recommend a water bottle to keep your drink really cold?

[SunInTheSkyYouKnowHowIFeel]

I've got a Chilli bottle which I love & keeps drinks really cold, but they are quite expensive, especially for children who are prone to loosing them etc. I want to buy another similar & have seem some cheaper alternatives in the supermarkets, do these cheaper ones work just as well, or does anyone have any other recommendations?

I bought a 720 Degrees water bottle for my mum in hospital as she didn't like the taste of the tap water, so I could fill up with iced bottled water every day. It was so good that I bought one each for the 4 of us as well. The kids are always surprised you can still hear the ice the next morning. But I think there are even better ones. Make sure it's got a wide neck so you can fit ice cubes in.

I've found Morrison's own ones very good.

Thank you, will check those out

I was going to recommend S’well but see they’re in the same price range. www.swell.com/ That said, they really do keep your drinks cold all day.

I use a Smash one from Sainsbury's, £6 I think and very good.
