On many occasions I have filled it with water out of the fridge, added some ice and it is still ice cold 36 hours later. Yesterday on one of the hottest days the ice cubes were still rattling around in it 24 hours later. It is that good my partner purchased one as soon as she saw how cold the drink kept in it. Comes with 3 lids including a blank lid, a 'chugging' lid and a straw lid I use the chugging lid and my partner uses the straw lid on hers none of the lids have leaked on either of us and include a carrying handle and are easy to change. It also includes a small brush to clean the straw part. The inside is stainless steel so doesn't have that nasty aftertaste that plastic bottles have. This bottle is cheap compared to some alternatives on Amazon with just as good if not better specifications. I haven't tried hot liquid in it but would presume it will also keep liquids hot and the blank lid would allow you to place soups in it for winter for easy pouring. The jacket and carrying strap are an added bonus the 1.8 litre version weighs approximately 2kg full of liquid. Very happy with it! ### ⭐⭐⭐⭐⭐ Just buy it *by on Reviewed in the United Kingdom 12 July 2026* Keeps hot things hot and cold things cold, good value for money and great you get different kids included, no leaks, no spills. Wide mouth makes it easy to clean. Black is good colour and looks smart. Easy to leave in the van at work and sip from it as and when you need which is very practical. Good quality materials and feels a lot more premium than its price point. Prefer this over my wife’s yeti which was just over double the price. ### ⭐⭐⭐⭐⭐ Absolutely Brilliant!! *by on Reviewed in the United Kingdom 5 July 2026* Absolutely amazing flask. I've personally only used it with cold water and the claims that it keeps it ice cold for 24 hours is absolutely true. It was well needed during the heatwave we have just had. I will point out though that this flask is not small at all so if you need something on the smaller size this isn't for you. It comes with cleaning pipes to keep it nice and fresh and 3 diffent types of lids which are perfect and do not leak at all. I can highly recommend this to anyone. ## Frequently Bought Together - Coolflask 128 oz Gallon Water Bottle Insulated with Straw&3 Lids, Water Jug Large Stainless Steel Metal Vacuum Wide Mouth for Sports, Gym or Office, Non-BPA Keep Cold 48H Hot 24H, Samurai Cyan - Coolflask 64 oz Water Bottle Insulated with Strap, Half Gallon Water Jug Stainless Steel with Straw & Spout Lids, Metal Large Water Flask, Keep Cold 48h Hot 24h, Leak Proof & Non-BPA, Prussian Blue --- ## 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/385692903-coolflask-gallon-water-bottle-insulated-with-straw-and-3-leakproof](https://www.desertcart.us/products/385692903-coolflask-gallon-water-bottle-insulated-with-straw-and-3-leakproof) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-08*
