S'wellStainless Steel Traveler - Triple-Layered Vacuum-Insulated Travel Mug Keeps Coffee, Tea and Drinks Cold and Hot - BPA-Free Water Bottle

i use the flask every day its has a nice simple design, it never leaks since there isnt the silly plastic piece which a lot of the flasks have, and it will keep your drink very hot for hours, I make my tea at 6 in the morning and take it to college its still almost too hot to drink by about 3 o clock

I absolutely love this flask - and use it pretty much every time I go out. The fact that it has a wider opening at the top means that I can easily add ice - I use it mainly for cold drinks as I like to always have a nice cold refreshing drink with me when I’m out and about. During last summer which was so hot I always had iced drinks with me - and they stay lovely and cold for hours in this flask as it’s great quality. I also get a lot of people asking me where I got it from - as it looks so good. I have two - and wouldn’t be without them.

Perfect and stylish

On a mission to reduce my plastic usage I decided on this S'well flask for my morning coffee. It is such a beautiful product and I love the shape of this flask compared to the more slimline flasks you usually get.I use this flask mostly for my morning coffee taking it into work and I'm now in such a routine of using it that it is saving me so much money buying coffees from cafes. The flask holds around two large mugs of liquid which sees my through the morning but I would say that it will only keep drinks warm for around 4-5 hours - but that isn't too much of a deal breaker for me.

The 350ml is the perfect size for a large flat white - which is my go-to drink in the morning. The lid provides a tight seal and the bottle is leakproof, but it does 'squeak' every time I open or close it. Seems durable, and apart from a few tiny scratches on the lid the bottle itself looks like new. Keeps my coffee warm for hours, and the wide mouth makes it easy to clean (hand wash only!). Very comfortable to hold and lightweight, quality materials. Knocked one star off because it is expensive.

The best at keeping drinks hot and cold, especially as it is wide mouthed so it can also hold ice cubes.

I love this bottle,and can put it in my bag without worrying that it is going to leak, which is the first bottle I've ever had that I've been able to do that with. Sadly, it doesn't keep drinks hot for as long as promised - please s'well, would you produce a neoprene sleeve to help with this?

Brilliant keeps drinks really cold, nice wide neck easy to put ice cubes in.
