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. Review: Built Like It Could Survive a Camping Documentary - 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. 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. ## Features - Thermos Vacuum Insulation: Unrivaled temperature retention for hours in our stainless steel water bottle.

Retained the heat very well, was still steaming a good 10 hours after making. Great bit of kit - recommend. Easy to pour, twist top so less less likely to break unlike previous other push top ones i’ve bought. ## Frequently Bought Together - Thermos 170287 Stainless King Flask, Copper, 1.2L - THERMOS Stainless King Vacuum-Insulated Compact Bottle, 16 Ounce, Midnight Blue - THERMOS Stainless King Vacuum-Insulated Food Jar with Spoon, 16 Ounce, Matte Stainless 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.tn/products/52265077-stainless-king-copper-travel-flask-1-2l-premium-leak-proof](https://www.desertcart.tn/products/52265077-stainless-king-copper-travel-flask-1-2l-premium-leak-proof) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-13*
