Review: Can’t go wrong with this! - Great flask, own quite a few different sizes in this range and my review applies to them all. Cant fault these I feel they are far superior to the glass vacuum-inner thermos range which has exploded on us previously while in a bag on a bumpy mountain bike ride. Also I don’t see much difference to the Stanley I have except for price. Collapsing handle means it fits into bags and takes minimal space. 1.2l capacity is great for a hike as not too heavy but enough tea/ coffee for myself and 2 teens. Easy to use, keeps liquids hot for more than the listed 12hrs. Caution needed for first few sips as drinks will pour piping hot! Haven’t used for cold drinks. Metal cup can be hot to hold but we like this as it warms cold hands in cold Scottish weather. I prefer to carry milk separately and pour on drinking as it tends to taste and smell odd if drinking your brew after 4/5 hours of it being in the flask. Also good for hot soup, for us 3, on the go. Colours are pretty accurate to what’s shown in listing and hold up well to washing, etc although we never put any of ours in the dishwasher. I did swap this for a different colour as the red was too red according to teen using it for DofE - went for army green instead which is lovely! And classic black for a friend. Very good value for money at full price but more so if you get it on discount
Review: Good - Excellent quality flask. I was impressed that my tea was still hot 24 hours later. Definitely worth the price. Recommended!

## Questions & Answers

**Q: 50 year guarantee is that correct ? do we have to send off any guarantee ?**
A: I sent mine back. After 18 months it developed a fault. 2 weeks later new one came. I was not asked to fill out an interrogation questionaire or quibbled at. Brilliant service. By the way, these flasks really do keep contents hot for 24 hours. Tested.

**Q: Hi I see this flask is available in 1.2L size and also in 'large' size.  Can someone tell what is the capacity and dimensions of the large flask**
A: I think what it is...is on the link you are using  thje green 1.2litres is a nomal flask the large one is one with extra protection...I have one of those and it holds the same but is tougher...They really do stay hot (or cold) prob longer than it states on the site... really pleased with mine

**Q: Is the cup stainless steel or plastic on the inside?. Thanks.**
A: It's stainless steel and the water stays hot for hours.

**Q: Why is the RRP so drastically different for the different colours?**
A: I have wondered the same thing myself, however, I do know that some colours are more difficult to produce and cost more, plus good adherence to the base metal can also involve further cost. You'd think they would work out the average and charge that for all colours but perhaps that would be unfair to those choosing the less expensive finishes.

### ⭐⭐⭐⭐⭐ Great quality flask
*by T***Y on 31 January 2026*

Great quality flask. Being of stainless steel , there’s no worry of dropping it and having broken glass like other flasks. I got this for my son, who is a builder and needs hot drinks in this weather. He is very pleased that the flask keeps hot all day and of the size. Would definitely recommend this flask.
