## Description

From the manufacturer

Review: 🏕️ The Ultimate Hot-Shot Flask That Defies the Cold! ☕ - Quick Breakdown: Pros & Cons Cons ❌ Exterior metal is incredibly lightweight and can dent if it takes a hard fall onto rocky ground. ❌ Lacks a built-in handle or carry strap which makes gripping it with bulky winter gloves tricky. ❌ The protective silicone rings on the body can slide out of place during rigorous cleaning. Pros ✅ Absolute thermal wizardry that locks in scalding temperatures for a full 24 hours. ✅ Innovative two-part pouring stopper regulates flow and completely stops messy splashes. ✅ Remarkably lightweight at just 390 grams so it never drags down a heavy backpack. ✅ Sleek and slim 8.2cm base diameter drops easily into standard water bottle side pockets. 🚀 Deep Dive: Why This Thermal Companion Dominates the Outdoors! Gear up, outdoor adventurers and caffeine enthusiasts! The Thermos Charcoal Ultimate Flask (900ml) is an absolute heavyweight champ in the world of temperature control, even if its physical weight is delightfully feather-light. 🌟 The real magic happens the moment the lid is twisted shut. This engineering marvel uses premium insulation to lock in extreme heat, keeping soups, coffee, or tea steaming hot for an entire day. No pre-heating required! It completely defies chilly weather, making it a reliable asset for long mountain treks, early morning job sites, or extended road trips. 🏔️🚗 Pouring is a dream thanks to the dual-component stopper mechanism. Instead of removing the entire plug and letting precious steam escape, a quick partial twist lets liquids flow smoothly and predictably without annoying drips or splatters. The outer lid pulls double duty as a perfectly sized cup, saving precious packing space. ☕ While the lightweight stainless steel shell requires a bit of care to avoid battle scars and dents from accidental drops, the weight savings on the trail are worth it. For anyone needing dependable, long-lasting thermal performance packed into a sleek, backpack-friendly frame, this charcoal beauty delivers the goods! 🎒✨
Review: Absolutly Flawless! - The best flask I never knew I needed. It keeps tea piping hot for literally hours. Very easy to pour from the spout and the fact I don't have to remove the lid altogether ensures drinks will remain hot. The lid feels secure when you twist it shut and does not feel like it will come loose when traveling to ensure it wont leak. With a 900ml capacity, it will keep me going all day without the need for top ups. Love the black and orange colour scheme and although it has protection top and bottom, I bought the official thermos pouch to store it in as the matt black finish is painted. It is just about the right size to fit in most car cup holders and easily fits in my backpacks side pockets. Hoping to enjoy drinking from it for years to come 🤞

### ⭐⭐⭐⭐⭐ Thermos Ultimate beyond compare and a shrewd long term investment an
*by S***R on 21 October 2025*

The Thermos Ultiimate drinks flask unique feature is in its ability to keep drinks scalding hot for 18 hours and hot for 24 hours. I purchased 2 of the smaller size (previous model) one for me and one for my wife about 15 or more years ago and they have never failed to impress on how hot they kept our tea or coffee. They are quite tough and resilient . Unfortunately I dropped mine once too many times , but without blinking instinctively reordered a new one within a heartbeat. Ooops, my eagerness caused me to order the larger 900ml size in error. I will keep it for hot water when we do go out together, as I drink coffee and she drinks Tea. I have already ordered the smaller size ( currently available from TK Max at under £20 and ordered on line for collection tomorrow I can’t wait). Originally I used it for work knowing wherever I was driving to around the country I had a hot coffee to enjoy and even if half drunk a very warm coffee at the end of the day before I started to drive home. I found the smaller size quite adequate to last me throughout the day providing 2 cups of coffee throughout the day. Life without one is almost inconceivable, that is how impressive the Thermos Ultimate flask is. I will keep the larger 900ml size and not return it as even though it is too large for my regular use as I’m sure it will come in useful on the odd but critical situation e.g. Overnight keeping water hot for the morning on a Trip or if I’m in bed unwell a hot drink to hand all day or overnight. It will also be great for cold drinks if going on a picnic or to the seaside with family . It may seem expensive but it truly is a long term investment. 20 out of 10.
