The vacuum insulated Stanley Classic Flask (0.47L) will keep hot drinks hot and cold drinks cold for up to 15 hours.

The folding handle packs down flat to help it fit easily into your lunchbag, whilst the insulated lid doubles as a 110z (325ml) drinking cup.

It sports the traditional looks that define a Stanley Flask, with its classic colouring and metallic finish - just like the flask your Grandpa used to use.

Flask purchased for son

I purchased this flask for my son who is doing Duke of Edinburgh and Ten Tors activities. This is a replacement product for a different flask that was previously purchased. Unfortunately the previous flask leaked and was therefore unsuitable. I was informed by the sales assistant that she owned this flask and that it did not leak and the liquid stayed very hot for an extremely long time. My son has not yet had the opportunity to use the product yet.

keeps the drink warm

tip - be sure to give the flask a good washing and cleaning prior to first use or you may get plastic tasting drink first time around.
I did clean the flask to what i thought was necessary but obviously not enough and the first drink was a little tainted.
filled up at about 8 am and still 'warm' at 2:30pm,, no danger of burning your mouth but still drinkable.

Perfect for a cold hike

Brought this for my partner for Xmas 2017; we filled it with hot mulled wine and hiked up Pen-Y-Fan on Christmas Day, it was around 4°C and the wind was immense at the top, but the flask had kept the wine as hot as when it was made. It’s possible to pour the flask without completely removing the inner screw top (just open a half turn) making for a more controlled pour in bad weather! The lid doubles as a cup and has a plastic rim that is comfortable to drink from. Both of us are really pleased with this flask and recommend it; you can get ‘cheap’ flasks but I think this is definitely worth paying extra for.

Excellent flask

Well worth the money. Have bought to replace a cheaper flask that didn't keep drinks warm. Easily keeps drinks hot after 6 hours out on a mountain. Fit nicely in side pouch of rucksack

Well worth the extra cash, it keeps your coffee really hot for longer than the cheaper equivalent.

Excellent and durable

Not too heavy. Keeps drinks warm for at least 6 hours. Would be confident to about 9. Testing mine at 14hours (it claims hot for 15hours) yielded only mildly warm results though.
It's not super compact, but its reasonably light, especially compared to the stanley master series options. And the lack of a handle means no handle to snag on stuff sliding in and out of a bag.
I love this flask and trust its construction to last me a while.

Stanley classic flask

Well impressed been looking for a good flask for ages. Ticks all the boxes, light weight, keeps tea piping hot, easy to clean, although it cost a bit more it’s worth it I’ve had too many cheap flasks in the past that let your tea go cold before lunchtime
