I purchased this as I require a flask for a winter camping trip to Norther Sweden and I need a container to keep water hot for half a day. Having had flasks before i know they work best if you prime the flask before adding the liquid you want to keep hot. So i though i would test the claimed period it says it can keep water hot for. I primed the flask with water just of the boil - 1/4 full swirled it around, put the cap back on an left to warm up for 3-4mins. I then emptied the flask and filled it with 1.5L of water just off the boil - temperature reading of 94'C 24hrs later i open to take a reading - 86'C (still very hot for drinks) 36hrs later i opened to take a reading - 70'C (still hot enough for my liking) 38hrs later reading was 67'C I decided that was enough testing :o) The flask well out performed my expectationsRead full review

A solid flask of the standard expectrd from ine of the mist reputable names in the business. High quality construction with a functional appearance. Great for a wide range of uses. Works really well, keeping the water hot for 24 hours and more. Previous flask used for 17 years and this one looks well capable of exceeding that. A great value for money purchase. I highly recommend buying this product.

Absolutely the best flask I've ever owned. Does exactly what is says on the tin. Keeps hot for 24 hrs no problem. I filled this flask after purchase just to try it. Filled at 6.00pm with boiling water and at 2.00pm next day I opened it up and water was still so hot I couldn't bear to hold my hand under it. Great product well worth the money.

I have used a number of different named flasks over the years, most claiming to keep drinks hot. Well this one definitely does. On a long journey the flask was made at 05.00 am and the drink was still hot at 6.00 pm. Need I say more !

ive used this flask countless times now and im still amazed how hot the remaining water is. The next morning when im emptying it the water can still make me hesitate because of the heat. ideal and highly reccomended for anyone working a 12 hour shift wanting a hot cupper when they wish.
