After using it regularly, I can honestly say this thing takes temperature retention very seriously. The first thing that impressed me was just how long it keeps drinks hot. I made tea early in the morning, forgot about it for hours, and it was still properly hot later in the day, not “technically warm if we lower expectations,” but genuinely hot enough to enjoy properly. Cold drinks hold up equally well too. Filled it with iced water during warmer weather and still had ice hanging around much later than expected. The insulation on this flask is great! Build quality feels excellent as well. It has that reassuring “solid chunk of stainless steel” feel that makes you think it could survive being dropped down a hill and still come back asking for more tea. Definitely feels durable enough for everyday use, commuting, travel, or outdoor trips. The twist pour stopper is also far more convenient than I expected. Being able to pour without fully removing the lid is one of those small features that becomes genuinely useful once you start using it regularly. Less heat escapes, less chance of spills, and less fumbling around when half awake in the morning. The built in cup is decent too. Simple, sturdy, and does the job well enough for tea or coffee breaks on the go. It’s also surprisingly comfortable to hold considering it’s attached to what is essentially a giant insulated steel cylinder. Capacity wise, 1.2L is excellent if you drink a lot throughout the day. It’s enough for multiple large cups without constantly refilling. The trade off is that it’s definitely not a tiny lightweight flask. When full, this thing has some heft to it. Not ridiculous, but you’ll notice it in a backpack. Leak proof performance has been great so far as well. I’ve carried it horizontally in bags without any unpleasant surprises, which already puts it ahead of several “premium” travel mugs I’ve owned. The red finish also looks really nice in person. Bright enough to stand out without looking cheap or overly flashy. Overall, this is an excellent flask if you want serious heat retention, durability, and large capacity. Reliable, practical, and built to last. The kind of product you buy once and end up using for years mainly because it stubbornly refuses to stop working properly. Review: Excellent heat retention and very practical for baby formula on the go - I bought this Thermos Stainless King travel flask mainly for preparing formula for my baby while out, after seeing posts online mentioning that it can keep water above 70°C for long periods throughout the day. The quality feels excellent and the stainless steel design feels very durable and well made. The matte black finish also gives it a sleek look while providing a nice grip in the hand. The heat retention is definitely the standout feature. It keeps the water hot for hours, which makes it extremely convenient when travelling or spending long periods out of the house with a baby. Knowing the water stays at a suitable temperature for formula preparation gives extra peace of mind. It seals very securely and has been completely leak proof for me so far, which is especially important when carrying it in changing bags or while travelling. It’s also easy to pour and drink from, and the overall size makes it portable enough for everyday use without feeling bulky. Another plus is that it’s straightforward to clean, I have purchased the OXO bottle cleaning brush for it, which makes cleaning much more convenient. Overall, a very practical and reliable flask that feels worth the investment. ## Features - Warning:Not suitable for children under 3 years.

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 ### ⭐⭐⭐⭐⭐ Built Like It Could Survive a Camping Documentary *by M***N on 14 May 2026* I bought this Thermos Stainless King mainly for long work days and trips where I wanted properly hot tea without paying service station prices for disappointing coffee.

Filled it with hot water, left it overnight and the contents were still so hot it was used to do the washing up. Highly recommended. ## 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.us/products/48869885-stainless-king-cranberry-red-drinks-flask-1-2l-24h-hot](https://www.desertcart.us/products/48869885-stainless-king-cranberry-red-drinks-flask-1-2l-24h-hot) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-26*
