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: Lasted 24 hour hot easy. - Excellent flask it kept our tea hot for 24 hours and didn’t leak at all, nice looking flask but wish it had 2 cups like our old one that we kept the cup from. £27 is the right price in my opinion. The flask is not too heavy when full and the handle is good quality too. ## Features - Thermos Vacuum Insulation: Unrivaled temperature retention for hours in our stainless steel water bottle.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Can’t go wrong with this! *by J***E on 21 January 2026* Great flask, own quite a few different sizes in this range and my review applies to them all.

The flask is not too heavy when full and the handle is good quality too. ### ⭐⭐⭐⭐⭐ Excellent heat retention and build quality, but quite bulky for everyday carry *by C***T on 18 March 2026* I’ve been using this flask for a couple of weeks now, mainly for tea, coffee, and herbal tea etc when I’m out and about. In terms of performance, it does exactly what you would want from a flask of this type. Drinks stayed properly hot for around 12 hours in normal use, still at a temperature I would describe as piping hot. I did not push it beyond that as I tend to drink it rather than leave it sitting, but for day-to-day use it has been very reliable. The capacity is generous at 1.2 litres, which is great if, like me, you get through a lot of hot drinks. That said, it is quite bulky and takes up a noticeable amount of space in a bag. The easiest comparison is that it feels like carrying a large bottle of fizzy drink, so it is something to be aware of if you were hoping for a more compact option. The design is well thought out. I particularly like the shape of the stopper, which is easy to grip and would be helpful when your hands are cold. The lid and pour mechanism work smoothly, and I have not had any issues with leaks. Overall, this is a solid, well-performing flask that keeps drinks hot for a full day of normal use. For a single person flask it is on the larger side, but if you want the extra capacity, it delivers exactly what you would expect. ## Frequently Bought Together - Thermos Stainless King Flask, Cranberry Red, 1.2 L 184803, Picnic Bottle - Thermos Stainless King Vacuum-Insulated Food Jar with 2 Storage Container Inserts, 47 Ounce, Matte Steel - THERMOS Stainless King Vacuum-Insulated Compact Bottle, 16 Ounce, Matte Steel --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.au/products/48869885-stainless-king-red-travel-flask-1-2l-premium-leak-proof](https://www.desertcart.com.au/products/48869885-stainless-king-red-travel-flask-1-2l-premium-leak-proof) --- *Product available on Desertcart Australia* *Store origin: AU* *Last updated: 2026-04-27*
